Question

What will be the angle of incidence if the Ray of light falls Normally on interface of two Media

Answer 1

Answer:

When light falls perpendicularly or normally on the surface of a glass slab, it goes straight. There is no bending of ray of light on entering the glass slab or coming out of it. In this case angle of incidence and angle of refraction is zero.

pls Mark me as brainlist plz plz plz

Answer 2

Explanation:

as first always says that Angle of incident,angle of reflection,normal always lie on the same plane.

And accordingly second law says angle of incidence is equal to angle of reflection
