Laws of Reflection

The two laws of Reflection are,

1. The first law of reflection states that the reflection point and the point of incidence are generally comparable. The reflected light will follow the same path if the original beam strikes the plane mirror at an angle other than the usual, like 90°. Thus, the first Law of reflection state that, the angle of incidence (∠i) is always equal to the angle of reflection (∠r).
2. The second law of reflection states that the point of incidence, the incident ray, the reflected ray, and the plane of reflection are all located on the same surface.

Laws of Reflection Formula

The Law of Reflection Formula is the term used for the essential relation stated in the Laws of Reflection i.e. the relationship between the angle of reflection and the angle of incidence. 

The Laws of Reflection Formula can be stated as:

Angle of Incidence = Angle of Reflection 

Reflected Angle = Incident Angle 

 ∠i = ∠r

where,

• ∠i represent angle of incidence
• ∠r represents angle of reflection

Angle of Incidence

Angle of incidence is defined as the angle made by the incident ray and the Normal. It is denoted using the ∠i.

Angle of Reflection

Angle of reflection is defined as the angle made by the reflected ray and the Normal. It is denoted using the ∠r.

For regular reflection. i.e. reflection from the regular surface, angle of incidence is always equal to angle of reflection.

We can easily calculate the angle of incidence and the angle of reflection by drawing a normal line that is perpendicular to the reflecting surface.

Laws of Reflection is a principle or rule that governs the phenomenon of reflection of light. The law of reflection states that a light ray will reflect off a surface at the same angle that it hit it when it comes into contact with it. The angle at which a light beam strikes a surface is known as the angle of incidence, and the angle at which the beam of light bounces off the surface is known as the angle of reflection. You can always determine how a light ray will behave, i.e., what direction it will go in and at what angle, by observing a single light ray approach and bounce off a flat mirror. In general, this is how the law of reflection works.

Now let us learn more about the Laws of reflection by understanding the concepts like What are the Laws of reflection? its formula, verification of laws of reflection, Laws of reflection for plane and rough surfaces, and examples of them.
