Question

calculate angle of incidence of light ray incident on surface of a plastic slab of refractive index √3, if angle of refraction is 30 degree
​

Answer 1

Answer:

Angle of refraction(r) = 30°.

Angle of incidence = i.

Refractive index (μ) = √3.

Refractive index (μ) = sinisinr.

⇒ √3 = sinisin30=sini12.
