Question

WHAT WOULD HAPPEN IF I THREW THE LIGHT ON THE MIRROR ALONG THE NORMAL

Answer 1

it will just reflect to the same path of normal

Answer 2

ANSWER :

When light is thrown at angle 90 or normal to the mirror, then we can see that the ray of light after striking the mirror will return in the same way.

It happens because when light strikes the mirror at angle 90 then, the incident angle and reflecting angle becomes equal. And since they become equal, the angle will be zero.

This is the phenomena that will occur if ray hits the mirror at normal.
