Yes for two scopes each for one eye
The light stays in the same medium when it is reflected, while it changes mediums when it is refracted.
When a light ray is incident on a boundary of greater density than the current medium, the reflected ray undergoes a 180 degree phase change
Magnification, such as in lenses: eyeglasses, telescopes,  microscopes. Raindrops refract different wavelengths of light at  different angles, to produce rainbows.
Yes, but they are avaible in specific country's. Its rubber isUKNOWN. Only found from Written records about it.
It wasn't a one man effort, inventing fiber optics. Works were inspired by John Tyndall who first discovered light can travel an irregular path through glass. Alexander Graham Bell later contributed. Heinrich Lamm in 1930 put the first fiber optic cable together stranding cable together and sending...
information in form of electrical energy 1st converted in light energy using transducer, then it is feeded to optical fibre in which light undergoes total internal reflection due to which their is no loss of energy through core & info. travels wid speed of light.
The minimum index of refraction for a glass or plastic prism to be  used in binoculars so that total internal reflection occurs at 45  degrees is 1.414
The element Erbium is used to boost the light. Here is a link to a YouTube video that explains it far better than I could. http://www.youtube.com/watch?v=E-DY_RT4fJ4&feature=youtube_gdata_player
No it's not that can actually cause severe damage to your eye or complete blindness.
Globally, from a macroscopic view, reflection has light (image)  reversing direction, whereas refraction has light changing  direction. Refraction is dependent upon the frequency of light.

The development of the first brake light is not actually known.They appeared in 1905 but took a while to catch on. By 1928 11 USStates adopted brake lights
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...
Basically. Light cant go through solid objects, or around it so it STOPS, then on the wall / behind the object there is a shadow casted.Density -High density --More Movement more vibration's.Low Density --Less Movement Less Vibration's.Loves ya xxx

The index of refraction, or optical density, is the ratio of the speed of light in a vacuum to that in a given material. Therefore, the index of refraction for this glass is equal to c / v = (3.0 x 10^8 m/s) / (1.6 x 10^8 m/s) = 3.0/1.6 = 1.88
Yes, you can. In fact, you should be able to see the planet with your naked eyes.
Simultaneous macular perception,fusion and stereopsis
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.
To get better images with large telescope mirrors. it is necessary to counteract the distortions caused by the atmosphere and gravitational/thermal stresses.
1: Fastest cable in sending and receiving data and information. 2: Small in size. 3: Water proof 4: Travel long distance (miles) 5: Last longer that other cables. by:kishon (Grenada)
Mirrors can also be used, but   1. reflection efficiency 95% at similar cost of manufacturing   2. can distort , cause fuzzy and dim images.
When a ray of light strikes an obstacle it changes its path this is called reflection of light whereas the bending of light ray while traveling from one medium to other is called refraction.
Light is refracted away from the normal while passing from denser(slow) medium to a rarer(fast) medium.At one angle called the critical angle the angle of diffraction is 900.After this the ray diffract at an angle greater than 90 i.e. it comes back to the slow medium.Whereas from faster to slower...

because it feels like it
A medium with a higher index of refraction, like diamond, is more dense than the medium with a lower index of refraction, like air. If the ray of light is moving from the less dense medium (lower index of refraction), to a more dense (higher index of refraction) the ray of light bends TOWARDS the...

Binoculars have one tube for each eye while a telescope only has one tube.
The "-ocular" in "binocular" is from Latin oculus, which means "eye." The 'n' belongs to the prefix bin-, which is from Latin bini meaning "2 at a time."
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.

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...
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...
Light travels at different speeds in different substances.Refractive Index is a measure of this.Refraction is the bending of light when is moves from one substance to another. Most commonly seen in Air/Water and Air/Glass since we have these around us a lot.

when light hits an object...for example a mirror..it"ll bounce back(reflection) but when light goes into a new middel...for example from air to water it'll cahnge directions and the speed of light may also change ( that's refraction)
It may, it may not. A neon lamp is close to monochromatic, but its ionised gas emits non-polarised light. A laser is the same - it's monochromatic *and* coherent, but the excited photons it emits are not naturally polarised. Generally, to get polarisation you need some kind of filter. Easiest...

1. Longer distance (up 40 km with single mode). 2. Usually higher transmission speeds. 3. It's not prone to the EMI. 4. It's very hard to tap it.
No, if the refractive indexes of the two mediums are exactly  identical it will be invisible.
Depends on the system. Can be very high.
binocculars are a tool that scientists can use to help them see things that are far away.
It's possible because modern binoculars began to be developed in 1854 and the first American settlers could have imported some binoculars from Italy or England if such thing was possible at that time.
Refractive index=Sin i divided by Sin r where r= angle of refraction i= angle of incidence Light rays hitting the boundary at an angle of 23° is refracted at 90° to the normal. Therefore, r= 90 and Sin 90° = 1 . This implies that Refractive index= Sin i =Sin21° = 0.36 Speed of light in...

When light leaves glass and enters air, it is travelling to an optically less dense medium. As it leaves the glass, the light rays will be away from the normal. Hence the angle of refraction is larger than the andle of incidence.

Binocular telescopes, or binoculars are instruments used to see objects in far distances. They are two identically symmetrical telescopes placed side-by-side, lined in the same direction allowing us to use both eyes. Most are minature in size to be placed in our hands, and others are not, the ones...
Binoculars were invented by Jan Lippershey in 1608. However, it  seems that Galileo may have come up with the original idea for  binoculars, including what lenses to use in them.
Change in speed of light Light does not travel at 3.0 x 108 m/s unless it is in a vacuum. In air, water, glass and diamonds it travels more slowly and bends as it changes from one medium to another. Diamonds slow the light a great deal. That's why the can appear to sparkle as the light bounces...
reflection is when light is bounced back(this can be done with a mirror)and refraction is the bending of light(like if you put a pencil in a glass of water it looks like it bends).
Refraction can separate white light into the spectrum of visible light from red to violet.
A monocular microscope has only one eyepiece and a binocular microscope has two eyepieces.
Refraction has to do with the curvature of light because the index  of refraction. Optical illusions are when you see things that  normally you wouldn't. Of course, I wouldn't consider an optical  illusion to be the results of brain damage, but rather of the  intact brain.
Fiber optics is quicker and has higher bandwidth but for long distances requires more infrastructure (but it is on the planet so is more easily repaired). Satellite communications is slower with lower bandwidth and noticeable delays, the long range capability is greater but parts of the...
because an opaque object is clear so light passes trough it. This is completely incorrect. Light does not pass through opaque objects. It is because the vibration of electrons happens so quickly that energy is passed on to other atoms. Thus, the wave is not re-emitted and no refraction occurs.
This could be easily understood with the idea of plane wavefront. Huygens have given the concept of wavefront. That has been defined as the locus of all points in the medium which get vibrated simultaneously and are vibrating in phase. More over ray concept is old one. Any ray of light will be...

Yes. The laws of refraction are laws of physics and as such remain constant, as long as the space between the media is constant.

yes all primates have binocular vision which allows them to have better depth perception
First off, the identifying numbers on binoculars are important. 5 x 20, for example, means that the binoculars magnification power is 5 (things will appear 5 times closer), and the objective lens (the one farthest from your eyes) is 20 mm across. For bird watching, a magnification power of 7-10 is...
