Nothing happens to light waves at all. UNLESS the two materials happen

to be right next to each other AND the light tries to cross FROM one INTO

the other one. Then things get very interesting.

What are some of the factors that go into a stock index?

Factors that might be used in several indexes may be given different weights in each index. Many market indexes will, at times, provide the same, or similar, assessments.


What materials are similar to alumina?

Materials similar to alumina include zirconia, silica, and titanium dioxide. These materials have high hardness, excellent chemical resistance, and thermal stability. They are commonly used in applications that require similar properties as alumina, such as in ceramics, refractories, and catalyst supports.


Do radio waves move faster in glass than in air?

Radio waves move faster in air. Radio waves are an example of electromagnetic radiation, just as light is. Just as materials have an index of refraction for light, they also have an index of refraction for radio waves. All electromagnetic waves have the same speed in vacuum whether they are radio, light or gamma rays. The speed of electromagnetic waves in a material is equal to the speed of light in a vacuum divided by the index of refraction for that type of wave. The index of refraction of glass for radio waves depends on the glass but is well above 1 whereas for air, it is more like 1.0001. A similar comparison can be made for visible light. The index of refraction can, of course, be measured, but for air and glass one expects them to be quite different because there is a huge difference in the densities of the two materials. Air mostly empty space between molecules and so one expects electromagnetic waves to propagate at a speed very close to the speed in empty space. As a very crude rule, one expects the long wavelength index of refraction for transparent materials to increase when the number of electrons in the medium increases. Caveat: Statements made here would have to be modified if the energy of the electromagnetic wave were near an energy where it was absorbed by the medium.

How is refraction and reflection similar?

Refraction and reflection are both processes that involve the bending of light. Reflection occurs when light bounces off a surface, while refraction occurs when light passes through a medium and changes speed, causing it to bend. Both phenomena are fundamental principles of optics.


Why does no refraction occur when the media have the same index of refraction?

Reflection happens only at the interface between two media, and two media with the same index of refraction act as if they were a single medium. Thus, at the interface between media with the same index of refraction, there is no reflection, and the ray keeps going straight. Continuing this line of thought, it is not surprising that we observe very little reflection at an interface between media with similar indices of refraction.


How are diffraction and refraction similar and how are they different?

Diffraction and refraction are similar in that they both involve the bending of waves. However, diffraction occurs when waves encounter an obstacle or a slit, causing them to spread out, while refraction occurs when waves pass through a medium with varying densities, causing them to change speed and direction.

How do you find the end of a rainbow?

No you can't because a rainbow is just a refraction of light, similar to the way the sky is blue.


Why prisms refract light?

Prisms are usually made of glass, plastic, and other similar materials.These materials are optically denser than our surrounding air.Thus refraction will occur.The speed of light in air and these materials are different.EXPLANATION:When a ray of light will enter a prism(optically denserthan air), the speed of light in the latter will decrease, and this decrease will cause the ray to deviate at a certain angle from the normal. This phenomenon is known as refractionSimply, when light passes from one medium(e.g air) to another(e.g glass prism), refraction occurs.


Is there anything similar to the DOW?

The Dow Jones Transportation Average, which was also created by Dow. Along with the NASDAQ Composite, the S&P 500 Index, and the Russell 2000 Index, the Dow is among the most closely watched benchmark indexes tracking targeted stock market activity. So yes, there are similar indexes which attempt to capture the movement and activity of the American stock markets.

How are refraction different how are they similar?

Refraction and reflection are both phenomena that involve the bending of light, but they occur in different ways. Refraction occurs when light passes from one medium to another and changes speed, causing the light rays to bend. Reflection, on the other hand, occurs when light rays bounce off a surface at the same angle at which they hit it.
