According to the law of reflection, the angle of incidence and angle of reflection are equal. Both these angles are measured with respect to a line normal to the reflection surface. If I understand the question correctly, the incident ray makes an angle of 60 degrees with the mirror surface, then the angle of incidence can be calculated as:

Angle of incidence = 90 - angle made with the mirror surface

= 90 - 60 = 30 degrees.

Since, angle of incidence = angle of reflection = 30 degrees.

The incident ray will have an angle of reflection of 30 degrees (made with a surface normal to the mirror surface).

The reflected ray will make an angle of 60 degrees (90 - 30 degrees) with the mirror surface.

Hope this helps.

Hi Mate!!!

We know angle of incident is equal to the angle of reflection.

Let that angle be X

x + x = 60

2x = 60

x = 30

So, the angle of incident is 30° and angle of reflection is also 30°..



! Have a great future ahead!!!!!
