Question

A ray of light is incident (normally perpendicular) on a plane mirror. Where will this ray of light
go
after reflection from the mirror?
plz tell me ​

Answer 1

Answer:

Also 90°.

Explanation:

Given: Angle of Incidence(i) = 90°[Since, incident ray is falling perpendicularly on the mirror].

Therefore, angle of reflection(r) = 90°.[Since, angle i=angle r]
