Question

. A ray of light falls on a plane mirror at an angle 30degree with the surface of the mirror. Using

a protractor, draw a diagram showing the incident ray, the normal and the reflected ray.

Measure the angle between the incident ray and reflected ray.


No spam or else I will report​

Answer 1

Answer:

The incident ray will have an angle of reflection of 30 degrees (made with a surface normal to the mirror surface). Angle of incidence = 90 - angle made with the mirror surface= 90 - 60 = 30 degrees. Since, angle of incidence = angle of reflection = 30 degrees.

Answer 2

Answer:

HIII EVERYONE

Explanation:

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
