Question

If an incident ray makes an angle of 30° with the reflecting surface then what is the angle of incidence.

Answer 1

HEY FRIEND ✋✋


WE KNOW THAT :

ANGLE OF INVIDENCE = ANGLE OF REFLECTION

SO IN THIS QUESTIONS IT IS GIVEN THAT

ANGLE OF INCIDENCE + ANGLE OF REFLECTION = 30°

THEREFORE ANGLE OF INCIDENCE = 30°/2 = 15°
