Why does no refraction occurs 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.

∙ 11y ago1There is refraction of light when light falls perpendicular, the speed is changed in the different media. Refraction is about the speed change, v1=c/n1 and v2=c/n2.

What will happen when two different medium of same refractive index?
The angle of incidence will equal the angle of refraction. If two medium have the same refractive index, light does not bend.
Why does red light travel faster than blue light in air?
Red light and blue light travel the same speed in a vacuum, however they travel different speeds when traveling through any medium other than a vacuum. In most media, blue light has a higher index of refraction (usually denoted with the letter n) than red light. The higher the index of refraction, the slower the light goes compared to its speed in a vacuum. This relationship is governed by the following equation: v = c/n where v is the speed of light in a particular medium, n is the index of refraction of light in that medium and c is the speed of light in a vacuum. Since red has a smaller n than blue in most media, red travels faster then blue in most media. The index of refraction is determined by solving Maxwell's equations for a particular frequency and a particular medium.
What occurs when light is dispersed?
Refraction occurs in the same 'direction' each time. The different colours are each refracted by different amounts. :)

When light moves from one medium to another it bendshowever there is one exception to this 'rule'?
it will not bend if the two media have the same index of refraction.
Is there a refraction of light in an the same media?
No.
Is the law of refraction the same for light rays going in either direction between two media?
Yes. The mathematical law involving the indicies of refraction n1 & n2 and the angles A1 & A2 as; n1 Sin(A1) = n2 Sin(A2) will work regardless of which way the light is traveling. Just associate the variables n & A with the correct medium.
How does a glass is made invisible?
submerge it in a liquid that has the same index of refraction eg. water.

Is the law of refraction the same for light rays going in either direction between the two media?
Yes. The laws of refraction are laws of physics and as such remain constant, as long as the space between the media is constant.
If a glass prism were in a medium with the same index of refraction would it separate wight light into different color?
No, it would not.

When is refraction of light not possible?
The bending effect called refraction happens when waves cross the boundary between two different media. However, there will be no bending if (a) the left and right sides of the waves encounter the boundary simultaneously or (b) the speed of the waves is the same in both media. This is because bending only occurs when one side of the wave overtakes, i.e. advances relative to the other.
