Its angle of incidence is 40°

Explanation:

  • Angle of incidence is the angle formed by any ray incident with the normal when incident on the surface
  • In ray optics we have reflection and refraction phenomena where angle of incidence is having great importance. According to angle of incidence reflection and refraction have different results for example if the ray of light incident on any given surface with angle of incidence 90° then it passes through the given material without deviating and reflect along the surface

Given, angle 50° is made with the surface

=> angle of incidence = 90°  - angle made with surface

=> i = 90°- 50°

=> i = 40°
