Optics

yes, most of the light will travel through, but some will reflect at a angle from where you point or place it. Also because that is how Thomas Edison saved his mother, his mother was dying and the doctor needed light to perform surgery so Edison realized that light must reflect off of glass, such as mirrors.

If I look to an object at a distance much bigger than the greater linear dimension of the object itself, it appears like a point.

Imagining to look through air, like we generally do on earth, we can apply the light rays approximation to study the phenomenon, neglecting the wave nature of light.

If the light rays have to travel a great distance it is possible that air density changes along the path. Since the air diffraction index depends on air density the light rays travels through a variable diffraction index field, so undergoing continuous diffraction causing the rays to have curve trajectories.

We can understand this phenomenon by imagining air composed by a very high number of tinny layers with a different diffraction index and designing the rays trajectories by evaluating diffraction every time the ray passes from one layer to the other.

Since our brain always assumes that the light rays trajectories are straight lines, curve light rays cause the brain to estimate erroneously the position of the object. As a matter of fact the object is located by constructing a wrong light ray trajectory linear and tangent to the real curve light ray at the point in which it hits the eye.

This is for example the mechanism causing mirages in the desert, where strong air density fluctuations can appear due to the high temperature difference between air near the sand an air far from the sand.

Probably more of a question for a university professor or something but I think it is an extreamly important technology because unlike copper wiring, fiber opticals are not suceptible to electical or magnetic interference. Also, with the development of LASER and LED technologies, optical fibers use far less electicity and interpreting information received is faster than copper. There is also, theoretically, no limit to the ammount of data that can be sent accross a single fiber.

Semiconductor lasers are used for different applications to solve various problems, such as, measuring in a direct way, the blood perfusion of body tissue. It is an instrument that can be used in the defense industry, internet applications and many other uses.

A good place to see pictures of light refraction is on Google Images or science websites such as National Geographic or ScienceDaily. You can search for "light refraction" or "photos of light refraction" to find a variety of images showcasing this phenomenon.

I'm unable to draw diagrams. However, in the refraction phenomenon of light, when light passes from one medium to another, it changes speed and bends at the interface due to the change in refractive index. This bending of light is what causes the refraction phenomenon.

"MIC" stands for Mode-Field Diameter in Fiber Optics. It refers to the diameter of the optical mode in a fiber, which affects the propagation of light signals within the fiber. A smaller MIC typically results in better signal quality and lower dispersion.

Light travels through fiber optics the same way it travels everywhere else, except when it scrapes against the inside of the cable it bounces off. Sort of like how a matchbox car goes down a plastic track. In fact, just like the toy car, the light will escape from the cable if it has to turn too quickly. The name for this maximum turn angle is called the "critical angle".

This "critical angle" is different depending on what kind of material is in your cable (glass, plastic, metal, etc) as well as what the cable is sitting in (Air, water, space, etc).

Coherent light can be produced without reflection and refraction by using a laser. A laser produces coherent light through a process called stimulated emission, where photons are emitted in the same phase and direction. This allows for the creation of a narrow beam of light with a specific wavelength and high coherence.

Optical Fibres are tiny cylindrical strands of glass that carry light rather than electrical energy. Fiber-optic cable is increasingly used for long-distance phone lines because it can carry large amounts of data, is not subject to crosstalk or electromagnetic noise, and cannot be tapped into without producing a noticeable drop in signal level.

* Glass and/or plastic cables connect to a light source and the light is carried from the source through the cable by a reflected inner lining. The diameter of the cables vary in milimeters and if bent sharply can break the integrity of the cable and diminish the light source. The cables can be cut to various lengths and the tips where the light comes out does not get hot. * Fiber Optic Fibers have been around for more then forty years, and since then they have become more cost effective and stronger. Plastic fibers are made with chemicals, the CORE is Polymethyl Methacrylate polymer (PMMA), and the CLAD is a thin layer of Fluorine polymer. The Core carries the light down the Fiber while the Clad is the reflective surface the light bounces off of! The diagram below shows what happens to light as it enters and travels through the fiber. Light enters through one end of the fiber and is "Reflected" to the other end, if the angle of the light is to great the light will not enter the fiber correctly and refraction will be lost. Skewed fiber is when the ends are not cut parallel to the 90-degree axis of the fiber. Light is also lost if the ends are not polished; to polish the ends of fiber you can use a 600 grit wet-dry sandpaper and finish with a 3m polishing film or a 1500 or greater sandpaper. The fiber has a 17% Clad which doesn't carry light, so the transmission of a one foot piece of fiber is in the area of 60-65%. * If light enters one end of a fiber, it will travel through the fiber with very low loss, even if the fiber is curved. The principle that makes this transmission of light work depends on the total of internal reflection. The light traveling inside the fiber center, or core, strikes the outside surface at an angle greater than the critical angle, so that all the light is reflected toward the inside of the fiber without loss. This allows the light to be transmitted over long distances by being reflected inward thousands of times. To keep the light from loosing its power and to avoid losses through the scattering of light by impurities on the surface of the fiber, the optical fiber core is covered or (clad) with a glass (or plastic) layer of a much lower refractive index; the reflections occur at the interface of the glass fiber and the cladding. * Tiny cylindrical strands of glass that carry light rather than electrical energy. Fiber-optic cable is increasingly used for long-distance phone lines because it can carry large amounts of data, is not subject to crosstalk or electromagnetic noise, and cannot be tapped into without producing a noticeable drop in signal level.

Resolution describes the ability of an instrument to separate two images that are close together. Higher resolution allows for better differentiation between the images.

No, it isn't one direction, otherwise there would not have been vibration at all!

In normal light, the electric field vibrates in planes which are perpendicular to the direction that the wave is moving.

In polarised light, the electric field vibrates in only one plane which is perpendicular to the direction that the wave is moving..

(3 dimension has been considered in the answer; this is why plane(s) have been used in the answer)

The future scope of fiber optics is promising with advancements in technology driving faster data transmission, increased bandwidth capacity, and improved connectivity. Fiber optics will continue to be essential in supporting high-speed internet, 5G networks, cloud computing, and other emerging technologies that rely on reliable and efficient data transmission. Additionally, fiber optics will play a crucial role in expanding broadband access to underserved areas and supporting the growth of smart cities and IoT applications.

Light will travel at a speed of approximately 200,000 kilometers per second through acrylic, which has an index of refraction of 1.49. This speed is calculated by dividing the speed of light in a vacuum (299,792 kilometers per second) by the refractive index of the material.

That's the simplest kind of polarization, and it simply means that all pieces of light - all photons - have the same orientation in space. For example, if the light shines horizontally, the light can be vertically polarized, or it may be horizontally polarized. Or at some other angle in between.

Ibn al-Haytham, also known as Alhazen, was a prominent Arab mathematician and physicist known for his significant contributions to the field of optics. His most famous work, "Kitab al-Manazir" (Book of Optics), laid the foundations for the modern understanding of vision, light, and optics. Ibn al-Haytham's experiments with lenses and mirrors helped debunk the ancient Greek theory of vision, leading to the development of the scientific method in optics.

Most Telecommunication uses electric pulses through wires. A little bit occurs through fiber optic cables. Physics describes the behaviors of both electricity and light. All of telecommunication is physics. Really everything is.

Yes, fiber optics are a type of internet connection that transmit data using light signals through thin glass or plastic fibers. This technology is known for its fast speeds, high bandwidth capacity, and reliability, making it a popular choice for high-speed internet connections.

The delay earth-GEO satellite-back to earth is always about 250 ms. This is very high

compared to delays in fibre optics. Nothing can change this fact as (currently) the

speed of light is the upper limit for the signal propagation speed and the distance of

the GEOs is almost the circumference of the earth.

Did you ever see glass? - Yes, it can be seen, therefore it is visible.

The best way to clean spirit optics is to use a soft, lint-free cloth with a little warm, soapy water to gently wipe the surfaces. Avoid using abrasive materials or harsh chemicals that could damage the optics. Dry the optics thoroughly after cleaning to prevent water spots.

Light is refracted more in a diamond when entering from air due to the large difference in refractive indices between air and diamond. This causes the light to slow down and change direction dramatically, resulting in the sparkle and brilliance that diamonds are known for.

When light travels from air to glass, it bends towards the normal due to the higher refractive index of glass. The ray diagram shows the incident ray coming from air, bending towards the normal at the air-glass interface, and then bending away from the normal as it exits the glass. This results in the light ray being refracted towards the surface normal in glass.

Selective reflectivity occurs when the wavelength of the light is equal in length. Hence 410nm will be highly reflected.

Mood rings exhibit a similar effect by using chiral nematic liquid crystals.
