Question

which of the following graph represents the correct variation of angles of incidence (1) and angle of deviation.

Answer 1

hi my name is piyush.

In reflection,

angle of incidence = angle of reflection. So, the angle of deviation = 180° - (angle of incidence + angle of reflection)=180° - 2* 50° = 180° - 100°= 80°

Angle of deviation = 80°
