Wave Optics

Question

Wired Faculty App

The speed of light in the medium is

maximum on the axis of the beam

minimum on the axis of the beam

the same everywhere in the beam

directly proportional to the intensity I.

Solution

B.

minimum on the axis of the beam

The speed of light at the surface or interface of the medium is maximum while on the axis of the medium is minimum

Some More Questions From Wave Optics Chapter

Let us list some of the factors which could possibly influence the speed of wave propagation:
(i) nature of source.
(ii) direction of propagation.
(iii) motion of source and/or observer.
(iv) wave length.
(v) intensity of the wave.
On which of these factors, if any, does
(a) the speed of light in vacuum,
(b) the speed of light in a medium (say, the glass or water) depend?
