Question

a ray of light falls normally on a plane mirror what is the angle of incidence pls answer in both diagram and text I am in class 7 so pls the answer must be long with diagram and text both I need ​

Answer 1

Answer:

When the light ray is incident normally on the plane mirror then by using laws of reflection angle of incidence is equal to angle of reflection. Hence, as the angle of incidence is zero degree angle of reflection is zero degree. Thus, reflected ray will reflect back in same path as that of incident ray

Answer 2

Thanks for the points, you can of course report it. I don't care...
