Question

If the angle between mirror and incident ray is 30 degree then what is the angle of deflection.​

Answer 1

Answer:

The angle between the mirror and the incident ray is 30 degrees. The sum of the angle of incidence and this angle (30) makes a right angle. So, the angle of incidence is 90 - 30 = 60 degrees.

Answer 2

To find:-

Angle of reflection = ?

Law of Mirror :-

Angle of incident = Angle of reflection .

Solution:-

Given,

Angle of incident = 30°

So,

from Mirror Law, Angle of reflection = 30°
