The ray of incidence is the light ray hitting the mirror plane and the ray bouncing off is the reflection ray. An incident ray is a ray of light that strikes a surface. The angle between this ray and...
The angle between the incident ray and reflected ray is known as angle of deviation due to reflection. This will always be equal to 2i. Here i is the angle of incidence.So if 2i = 90 then i = 90/2 =...
