Question

what is the incidence angle
always equal ?​

Answer 1

• When light is reflected from a surface, the angle of incidence is always equal to the angle of reflection, where both angles are measured from the path of the light to the normal to the surface at the point at which light strikes the surface. This equality is known as the law of reflection.

Answer 2

Answer:

Here is your answer.

Explanation:

When light is reflected from a surface, the angle of incidence is always equal to the angle of reflection, where both angles are measured from the path of the light to the normal to the surface at the point at which light strikes the surface. This equality is known as the law of reflection.The angle of incidence is equal to the angle of emergence. This is always true, providing that you are using a glass block with parallel sides. The incident ray will also be parallel to the emerging ray.
