The sine ratio plays an important part in the refraction of light at the interface of two media through which the light travels - such as the interface between air and the glass of a lens.
Short Wavelength light
...physics ...it was not invented, merely discovered. its one of the many phenomenons of life
no the refractive index of glass is nearly about 1.5 .for crown class its nearly about 1.55
A convex lens is a lens that is wider in the center and then gets smaller towards the circumference witch is the outer edge of the lens.
You can't see anything in the absence of light.
Smith Optics is an upscale manufacturer of, primarily, sunglasses. The company also makes specialized goggles, such as for skiing or motorsports, and has lens, accessory, and even apparel lines.
Yes, the wavelength of the light limits the maximum magnification of a microscope. Using visible light, the limit is about 1200 to 1500X.
Anything that doesn't appear black is reflecting some light to your eyes.
The sunlight hits the glass of water and then the light disperses out as a spectrum of colour (rainbow). This is because sunlight is white light and white light contains the 7 colours of the rainbow. When it hits the glass the colours refract and disperse out as the spectrum of colours, which we see as a rainbow.

There are 5 different possibilities: if the object is beyond the centre of curvature of the mirror (C), then the image is smaller and inverted; if the object is at C, then the image is the same size and inverted; if the object is between C and the focus of the mirror (F), then the image is larger and inverted; if the object is at F, then there is no image; if the object is… Read More
An aperature OS size a illluminated by a parallel beam sends diffracted light into a angle of approximately ~y/a. This is the angular size of the bright central maximum. In trevelling a distance z, the diffracted beam therefore acquires a width zy/a due to diffraction. this gives distance beyond which divergence of the beam of width a becomes significant. Therefore, z ~ a2/y we define a quantity ZF called the Fresenls distance by the following… Read More
Polarization is the aligning of vibrations in a transverse wave, usually by filtering out waves of other directions. Polarized light waves only travel vertically or horizontally -- when combined at right angles they block each other out and no net light can be detected.
It is the bending of light

The 'Father of Modern Optics' is Ibn-al-Haytham (known as Alhazen or Alhacen in west). Abu 'Ali Al-Hasan bin Al-Haytham (965-1040 C.E.) was one of the most profound physicists (polymaths), whose contributions to optics and scientific methods are truly remarkable. Ibn Al Haytham is known as Alhazen or Alhacen in the west. He was born in Basrah and is thus also known as Al Bastion. He made a practical examination of the passage of light through… Read More
Less expensive - Several miles of optical cable can be made cheaper than equivalent lengths of copper wire. This saves your provider (cable TV, Internet) and you money. Thinner - Optical fibers can be drawn to smaller diameters than copper wire. Higher carrying capacity - Because optical fibers are thinner than copper wires, more fibers can be bundled into a given-diameter cable than copper wires. This allows more phone lines to go over the same… Read More

Fiber Optics by a long shot.
A hotlink is a direct link to an image on someone else's web server. For example, if you saw an image that you like in one of these blinkies resources and you put the image on your weblog using the image URL source of that other person's site, then you are hotlinking. And, unless the owner of that site permits this, then you are stealing bandwidth, which is unacceptable. The right thing to do, if… Read More
Different wavelengths refract at different angles when they pass through an interface (the meeting surface of two different media, or objects through which light passes) according to a variation of Snell's law. Because the light encounters two interfaces - one going in, one going out of the prism - it is refracted twice. The first refraction spearates the colours initially and the second spreads them even further apart.
No one seems to know....
The refractive index of water is 1.333. Refractive index n = c/v where c is phase velocity of a wave in a vacuum and v is the phase velocity of the wave in the medium. If precision is needed, then more variables come into play and n will change slightly. The temperature of the medium, the frequency of the light, etc... all can come into play.
Light exhibits wave characteristics. It is a characteristic of waves to travel in the direction of higher density. Light will bend towards the thicker parts of the glass. To be honest, there is no easy answer why that happens unless one wants to resort to quantum mechanics which is above the heads of most. White light is composed of a variety of frequencies. The wave rule is "longest is strongest" so the longest wave lengths… Read More
Refraction occurs when light enters a medium with a different refractive index (eg. air - glass) the different density of the material causes the speed of light to decrease causing a change in direction. This occurs with other waves also, not just light.
In the UK, spirit-dispensing optics used to be unsealed, and unscrupulous landlords used to put silver coins in them to reduce the amount of spirit dispensed.
Use Snell's Law. Snell's Law is: Sin i divided by Sin r, where "i" is the angle of incidence and 'r" is the angle of refraction.
terms realated to refraction of light are * interface * incident ray * refracted ray * point of incidence *normal *angle of incidence * angle of refraction *angle of deviation
Good optical fiber is made of glass, but inexpensive fiber is sometimes made of plastic.
To connect the PS3 to a HDTV you need an HDMI cable if your HDTV has an HDMI connection, if it doesn't you need a PS3 component cable.
One difference between reflection and refraction is direction. Reflection bounces the wave back towards the source while refraction deflects the wave away.
A radio telescope
The Sun's light enters the Earth through refraction,because if it wouldn't enter earth only if it reflected.
optical power means living
The Sun's energy arrives through space via the mechanism of electromagnetic radiation.
Monochromatic means that it has only frequency. Polarized is definition for light which has its electric and magnetic vectors oscillating in a certain way (linearly polarized, elliptically and so on) but it might have many frequencies included. In the same time monochromatic light can be polarized.
No, although their existence may be helpful to those who require parts which "edmund optics" sells.
Monochromatic polarized light is just light of uniform frequency. It is always polarized because with only one frequency of light, the phase difference between the components of the wave is constant.
it can, for instance selling fire to things through glasses can work with refracted light
Yes it can. refraction of light is where light energy is condenced into a fine are... this is called the point of refraction... this occours for example if a magnifine galss was being held over an area the thinnest part of the light going through is the point of refraction. as the the light is most condenced here it becomes hot. therefore when refraction occours over a long period it can for example grass or… Read More
It depends on the refractive index of the plastic. There are many different kinds of plastic and they do not have the same refractive index.
It is because the glass has more refractive index than air which makes the light bend more through glass than air.
No one invented light. Light has existed since the beginning of time. It is a natural physical phenomenon, a manifestation of a portion of the electromagnetic spectrum Tomas Edison invented the first light bulb. Thomas Edison invented the lightbulb
The Lens is the image-forming device on a camera. The lens bends light rays to project an image onto a light sensitive medium, which may be any of several forms, including film, sensitized glass plate, or electronic sensor. The Diaphragm is a variable opening which controls the quantity (brightness) of light falling on the light sensitive medium. The Shutter controls the length of time light is permitted to fall on the light sensitive medium. It… Read More

Likely never until they advertise your area as being scheduled to have fiber service added. Right now the market for fiber is exceedingly stale, with no providers bothering to increase their networks due to cost issues. This lack of competition is no doubt hurting the consumer, but past complaining, there isn't much that can be done.
Because the chloroplasts are red.
There is a phenomenon in optics called "total internal reflection". Suppose a light ray is in some medium like glass and is about to exit into the air. If the ray is incident on the glass/air surface at a large enough angle then it gets totally reflected back into the glass. This phenomenon is used in fibre optics. Light is sent into the end of the fibre at an angle, so it travels a short… Read More
Wearing reflective clothes is very helpful whilst cycling as it is bright and this will cause less accidents to take place. It also helps drivers to see cycle's at night so there would be fewer accidents and injuries. Part of the surface of the garment may have retro reflective stripes. This way they become much more visible in the dark for observers near a light source, such as the driver of a car with its… Read More
Asumming the polariser is vertical, then 100% of vertically polarised light passes through it and 0% horizontal light passes through it. Simple so far. For 45 degree light it gets weired. Each photon of light has a 50:50 chance of making it through. It is impossible to tell if a particlular photon will or will not pass through. it is totally random. If it does pass through however it will change its polarisation to vertical… Read More
Value always depends on condition. In this case, if you have a standard A-Bolt, you would be looking at $600 to $700 if you are selling.
Fiber Optics are unable to be tapped like radio frequencies. It is capable of high speeds and full duplex. Light is modulated and sent through them.
The refraction of light is the change in direction of a light ray when it crosses a boundary between two transparent substances. Refraction of light is the change in direction of a light ray due to a change in its speed as it goes from one medium to another. The speed and wavelength of a light ray change when this occurs, but the frequency remains the same. When light travels from denser medium to rarer… Read More
Of course it does. You are looking at a REVERSE image.
Several people contributed to the making of fiber optics, including Alexander Graham Bell. The first person to actually make it work, however, was a medical student named Heinrich Lamm in 1930.

Unpolarized light has electromagnetic waves vibrating in all directions perpendicular to the direction of propagation. A polarizing filter only transmits light that is polarized along the same axis as the filter's axis. (Note that a polarizing filter also partially allows some orientations through that have some component of its axis along the same axis as the filter). The transmitted light thus constitutes half of the incident unpolarized light. Think of it like this: unpolarized light… Read More
Without refraction of light eyes cannot see and eye sight problems could not be rectified. Camera cannot function. Pojector fails to magnify the image and projects it on the screen. Optical fibre could not have been made into reality.

Used mostly in endoscopes to see inside a patients body. A light is usually passed down to illuminate the cavity. They can also be used to make phone calls or print images of the surgery.
During refraction, light follows particle nature. When a pair of light particles, attracted to each other, travel from a rarer medium to a denser medium obliquely, the particle that reaches the denser medium first, slows down. As a result, the light ray bends towards the first particle, which is nearer to the normal. Hence when light passes from a rarer medium to a denser medium, it bends towards the normal. A similar situation takes place… Read More
Refraction of light allows for the change of appearance of an object
If a material (in this case air) is transparent, it means there are no electrons which can be excited by an amount corresponding to the energy in the photons (light particles).
Is this Jeopardy? OK I'll bite = "What is...a mirage?"
IMAGE! image means that it is a image of something or some one and it has been put into an image.
Mirrors Because if they didn't, they wouldn't be mirrors; they'd be windows -- or walls! Perhaps you wish to know how they reflect or why some surfaces reflect whereas others don't. There are basically three types of surfaces: those that absorb light, those that reflect it, and those that neither reflect it nor absorb it. Not counting "black holes," there are no objects that absorb all light perfectly or reflect all light perfectly or pass… Read More
Using Snell's law, n(1)=(n(2) x sin angle (2)) / sin angle (1). n(1)= The refractive index of the more optically dense medium. n(2)= The refractive index of the less optically dense medium. angle (1)= The critical angle of the two mediums. angle (2)= 90 degrees since when light is at the critical angle it undergoes total internal reflection. Since sin 90= 1, this can be ignored, resulting in n(1)= n(2) / sin angle (1)
The first working laser was demonstrated on May 16, 1960 by US scientist Theodore Maiman at Hughes Research Laboratories. Since then, lasers have become a multi-billion dollar industry. By far the largest single application of lasers is in optical storage devices such as compact disc and DVD players, in which a semiconductor laser less than a millimeter wide scans the surface of the disc. The second-largest application is fiber-optic communication. Other common applications of lasers… Read More
The angle of incidence is the angle at which a ray of light (which is not at right angles to a surface) strikes a surface. The angle of refraction is the angle at which a ray of light, having passed through a surface, travels through the body of a substance. Normally the angle of incidence and the angle of refraction are not the same.
shadow is a black areashadow is formed when a opaque object is come in the path of light When light passes through opaque object, some of it would be blocked and form a shaedow.The shadow is formed according to the shape of the object as light moves in straight line. When light source is blocked by an opaque /translucent object a black spot is formed on the opposite side of the light source ...that black… Read More
Formerly, endoscope optics consisted of a series of thin converging "relay lenses", creating a succession of images in the air spaces between them. Following the innovation by Harold H Hopkins, the thin lenses in air were replaced by thin air lenses in glass. In other words, each lens consisted of a rod, with convex polished surfaces at each end. This increased the light throughput, and avoided the metal spacer rings needed in the old design… Read More
Not much, except mabey clearer glass and better reflecters. Reflectors? That doesn't make sense to me, as light in optical fibers is transmitted by refraction not reflection.
no need to wear goggles
Well, Newton itself proposed that photons went changing betwen two states, one for reflection and another one for refraction. ¿But what would it mean exactly? Perhaps in the reflection state the photon would "feel" a repulsive interaction about matter, while in the refraction state it would be attractive. ¿But how to avoid photons interacting randomly with any near particle or nucleus scattering themselves through the glass or the prysma? The answer to this could be… Read More
The sources of light are 1. Natural source of light 2. Artificial source of light Light (a form of electromagnetic radiation) is produced when an electron moves from a high energy state to a lower energy state. Light is produced by the release of energy, either nuclear, chemical, mechanical, or electrical energy. Light consists of packets called photons, but also acts as a wave with a specific wavelength and frequency.

Why is there a need for an AD converter in fiber optics communication?
There seems to be some confusion here! Visible light was being used - to see things, for example - millions of years before optical fibres were invented!

There are many theories for who invented the first pair of eyeglasses. There is evidence of eyeglasses in China from 1270, and the Chinese claim that they imported spectacle technology from the Middle east in the 11th century, but there are also some theories that they were first invented in Italy between 1280 and 1300.
Hi, Fiber Optics transmit signal using lights rather than electic current, so when signal passes though an optical fiber cable, it does not generate electric or magnetic field around it, and it is not affected by surrounding magnetic or electric fields Adv of optical fiber is that they are immune to noise, signal passes at lights speed, and no signal power is lost along the transmission line.
One fiber optic strand is made of glass. It is quite small and the light actually passes through an area within the core of the strand. Data is pushed through (zeros and ones) and data can be 'piggy backed' with other data. Think of a prism and all the data is the colors in the prism. The computer systems will take all the data (colors) and condense them into one (white light) and push them… Read More

Light that bounces off of something, mostly mirrors. It looks like a ball bouncing off the ground.
They also learn to compensate for refraction. When they plunge into the water, the eyes are protected by a membrane. So they actually catch their prey blind, relying on touch to decide when to snap their bills shut. They then fly straight out of the water with their prey in their bills. This was from the website: http://www.naturia.per.sg/buloh/birds/Alcedo_atthis.htm
Translucent means light passes through the medium, but the light is diffused so that object beyond cannot be seen clearly. Transparent means that light passes through the medium and is not diffused and objects beyound can be seen clearly.
Snell's law is the first law of optics, and also known as the law of refraction. It is a formula used to describe the relation between an angle of incidence and refraction, when referring to light.
It is because that is what transparent means!
