Question

Define the angle of incidence.

Answer 1

Answer:

angle of incidence is an angle made by a light ray or wave hitting a surface and the line perpendicular to that surface. An example of an angle of incidence is the angle between a light hitting a table and a line perpendicular to the table.

Answer 2

Angle of incidence

Explanation:

An incident ray is a ray of light that strikes a surface. The angle between the incident ray and the perpendicular or normal to the surface is the angle of incidence. It is represented by the symbol i.

r stands for the angle of reflection, which is the angle between the reflected ray and the normal.

As per the laws of reflection, the angle incidence = angle of reflection.

∠i = ∠r
