Light enters from air into a given medium at an angle of 45° with interface of the air-medium surface. After refraction, the light ray is deviated through an angle of 15° from its original direction. The refractive index of the medium is :
Text Solution
Verified by ExpertsThe correct answer is:
C
D=i-r
15° = 45-r 
r = 30°
n 1 sin i = n 2 sinr
1 sin45° = 
sin30°
