What is the reflection of light. State it's two laws with diagram
Answers
The Law of Reflection states that the angle of the incident light ray is equal to the angle of the reflected light ray. To understand what these angles and light rays stand for, consider the following diagram depicting the law of reflection. In this depiction, the blue band represents a mirror, which reflects rays of light.

Reflection
The most important thing about the law of reflection is shown as a dashed line in the figure labeled the normal. The normal line is just a line drawn to the surface of the mirror that makes a 90 degree angle to the mirror. This line is used as a reference point for all of the angles in the law of reflection.
The incident ray is the beam of light that initially strikes the mirror and the reflected ray is the beam of light that bounces off the mirror after striking the mirror. The angle of incidence is the angle that the incident ray makes with the normal and the angle of reflection, or reflected angle, is the angle that the reflected ray makes with the normal. The equation for the law of reflection is given by the following formula:
The angle of incidence equals the ray of reflection.
Law
So this law states that any ray of light that strikes an object will reflect off the object such that the striking or incident angle is identical to the reflecting angle (as measured from the normal).
