प्रश्न

A ray of light strikes a plane mirror at an angle of 40° to the mirror surface. What will be the angle of reflection?

उत्तर

he angle of reflection is 500, in accordance with the first law of reflection, which states that the angle of incidence is equal to the angle of reflection.
Here, the angle of incidence = 90o - 40o = 50o( the angle of incidence is the angle between the incident ray and the normal).
