Question

a ray of light goes from air into a medium with angle of incidence is 60. if the light ray refract in the medium at the angle of refraction 30 . find the refractive index of medium​

Answer 1

Answer:

n(air)×sin60 = n(medium)×sin30

where n is reflective index

for air n=2

1×√3/2=n×1/2

hence n is √3 or 1.732
