Answer 2

Hola mate! Here is your answer:

Given:

Refractive indices

P - 1.50

Q - 1.36

R - 1.77

S - 1.31

To find:

Medium in which speed of Light is minimum.

Solution:

Speed of light is inversely proportional to Refractive index of Medium

So speed of light will be minimum in medium having highest refractive index

So answer is Medium R

Hope it helps!
