1 of 1

Analyzing +4 | -1

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R
Assertion A: The phase difference of two light waves change if they travel through different media having same thickness, but different indices of refraction.

Reason R: The wavelengths of waves are different in different media.

In the light of the above statements, choose the most appropriate answer from the options given below

View answer and explanation

Correct option: D

Both A and R are correct and R is the correct explanation of A

Option C (3r) is correct because the particle travels from its extreme position to the origin and then to the opposite extreme position, covering a total distance of 3r.

In refraction, light waves are bent on passing from one medium to the second medium, because, in the second medium A double convex lens is made of glass which has its refractive index 1,45 for violet rays and 1.50 for red rays. If the focal length for violet ray is

20 \mathrm{~cm}

, the focal length for red ray will be Which light rays undergoes two internal reflection inside a raindrop, which of the rainbow is formed?
