Question

If an incident ray makes an angel 40° with the mirror,then what is the angle between incident ray and reflected ray

Answer 1

Answer:

Common mistake made by students is they don't read the question before attempting an answer.

Explanation:

The question clearly states the angle made by the light ray with mirror is 40°. This is NOT angle of incidence. Angle of incidence is the angle made by light ray with the vertical line drawn from the point where it lands on the mirror. This is 90 - 40 = 50°.

Now:

Angle of incidence = Angle of reflection = 50°

So, light bends by 50 + 50 = 100°

:-)

Answer 2

Answer:

angle of incidence=50deg.

Angle between incidence Ray and reflected Ray=50+50=1000deg.
