Question

Rays of light are entering from air to water. If the angle of incidence at the surface separating two mediums is 70°, find the sine of the angle of refraction of light in water. Absolute refractive index of water is 1.33. (Given Sin70 = 0.939, Cos 70 = 0.342) solve and show steps

Answer 1

Answer:

SinA/SinB = 1.33

A = 70°

Sin70° = 0.7738

SinB = 0.7738/ 1.33

SinB = 0.5818

B = 35.57°
