JEE PHYSICS MCQ: RAY OPTICS

1 Medium

1 of 1

Understanding +4 | -1

Assertion : A beam of white light when passed through a hollow prism, cannot give spectrum.

Reason: Because refractive index of air inside and outside the prism is same, so no refraction and hence no deviation will take place.

View answer and explanation

Correct option: A

If both Assertion and Reason are true and the Reason is a correct explanation of the Assertion

Option A is correct because a hollow prism with the same refractive index inside and outside will not cause refraction.

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

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