Question

the glass angle of incidence is 30° find angle i and angle r​

Answer 1

Answer:

This can be determined using Snell's law which states: Refractive index = sin i/sin r ( where i is the angle of incidence and r is the angle of refraction). So r = sin-1( 0.33) = 19.27°.

Answer 2

Answer:

angle of incidence = i = 30°

according to the law of reflection,

Angle of incidence=angle of reflection

Angle of incidence=angle of reflection VIZ,. i = r

therefore angle of reflection is 30 °
