Question

In the figure below, PQRS denotes the path followed by a ray of light as it travels three media in succession. The absolute refractive indices of the media are μ1, μ2 and μ3 respectively. (The line segment RS’ in the figure is parallel to PQ). Then:

Path followed by a ray of light which travels three medium

Path Followed by a Ray of Light Which Travels Three Medium

In figure PQRS denotes the path followed by a ray of light as it travels three media in succession. μ1, μ2 and μ3 are the absolute refractive indices of the three mediums.

Choices

Choice (4) Response

μ1>μ2>μ3

b.

μ1<μ3<μ2

c.

μ1<μ2<μ3

d.

μ1=μ3<μ2
