These are associated with LIGHT except one?

• Strength
• Beauty

• Color

• Image

It is the ray of light approaching the mirror.

• incident ray

• normal

• reflected ray

• All of the choices

It is the ray of light leaving the mirror.

• incident ray

• reflected ray

• normal

• All of the choices

It is a line that can be drawn perpendicular (at right angle) to the surface of the mirror. The normal line divides the angle between the incident ray and the reflected ray into two equal angles.
