Question

A vertical ray of light strikes the horizontal surface of some water what is the angle of incidence what is the angle of refraction

Answer 1

Answer:

angle of incidence = angle of incidence = 0°

Explanation:

Because the light ray is normally incident on the water surface

Answer 2

Explanation:

the angle of incidence is 0°

(angle of incidence is the angla made between incident ray and normal)

since the incidence is incident 90° to the surface that is the normal to the surface

so angle of incidence is 0°

angle of refraction is 0°

(similarly as incident ray)
