Question

Which of the following colors has the maximum refractive index?
A.Red
B.Violet
C.Green
D.Yellow

Answer 1

The index of refraction fluctuates with frequency, it doesn't change as the light goes starting with one medium then onto the next, as violet shading has the briefest wavelength thus the refractive index is greatest for it.

Complete answer:
The correct answer is B.
The index of refraction is a proportion of the speed of light in a medium. Since light ventures slower in a medium than in void space, it follows a way to limit the time it takes to make a trip from one highlight point inside another medium. This expects light to twist, or refract, at the interface between two materials.
$n=\dfrac{c}{v}$
Where n= index of refraction
c = velocity of light in vacuum
v = velocity of light in medium
This is like how a lifeguard will run along the shore of a lake until he's a lot more like an individual in trouble as opposed to plunging legitimately in because he can run a lot quicker than he can swim.

He doesn't follow a straight line to get to the individual since he needs to limit the time it takes as opposed to separate the ventures. Light does thing likewise. The refractive index relates how rapidly light goes through a given medium.

Refraction happens because light goes in various media with various speeds. This is a factor of the refractive index of the particular material.

The more noteworthy the refractive index, the slower the speed of light in that material. At the point when light enters from air into any material, the progress is from a mode of the lower index to a mechanism of a higher index.

Note: These outcomes in an easing back down of the speed of light. In the above condition, this would be reimbursed by a similar decrease in the wavelength. This shortening of the wave unexpectedly makes the light twist "inwards" or toward the ordinary (opposite pivot to the outside of the material). On the other hand, when light changes from higher index to bring down the index, wavelength expands to make up for the speed up light, consequently bringing about light twisting endlessly from the ordinary.
