Question

If the angle of incident is 30 degree determine the angle of refraction

Answer 1

Answer:

The angle of incident is 30° determine the angle of refraction is 19.27°

Answer 2

Answer:

the angle of refraction is 19.27°

Explanation:

this can be determined using Snell's law which states:

refractive index = sin i/ sin r

(since the medium has not been mentioned here, we consider it to be glass [default medium])

refractive index of glass = 1.5

1.5=sin 30/sin r

sin r = 0.33

so r = sin -1(0.33) = 19.27°
