Laws of Reflection
1.
The perpendicular line, the reflected ray, and the incident ray, all lie in the same plane.
2.
The angle between the Perpendicular and the incident ray ( i.e., angle of incidence ) is equal to the angle between the Perpendicular line and the reflected ray (i.e., angle of reflection ).

Definition of Reflection Law
Have you ever wondered why you are able to see your reflection in a mirror or why you see things reflected in the first place? An even more important question is why do we even see a table, or a chair or our phones sitting on the table? The answer to these questions happens to be one of the simplest laws in physics; it is called the law of reflection.
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).
More on Reflection
The law of reflection tells us that light reflects from objects in a very predictable manner. So the question is, why do we see objects like a table or a chair? These objects do not produce their own light, so in order for us to see any object, light must strike the object and reflect from the object into our eyes. More specifically, in order for us to be able to see objects, the light reflecting off an object must make its way directly to our eyes. So how does the light get from the object to our eyes? It does so through one of the two types of reflection: specular and diffuse reflection.
