Question

What is the angle of incidence if a ray of light
is incident normal to the surface
separating the two media?​

Answer 1

angle of incidence is 0 degrees

Explanation:

since normal is a straight line , so and angle is incident to normal , so the angle is 0 degree

Answer 2

Answer:

the angle of incidence and normal and angle of reflect ray all lies in the same plane and the angle if reflected ray is equal to angle if incidence
