Foe the same value of the angle of incidence thwe angles of refraction in the media A B C are 15 25 35 degrees respectively. in which medium would it be the velocity of light muinimum ?give reason to ur ans?

Speed of light in a medium v and refractive index μ of that medium are related as follows
refractive index is given by
for a given angle of incidence, angle of refraction is less in a medium compare to other medium means refractive indexof that medium is more.

hence in the given problem medium A is giving minum angle of refraction 15°. Hence refractive index of medium A is highest.

if refractive index is maximum in medium A means, speed of light is minimum in medium A
