Law of Reflection

The law of reflection states that the angle of incidence is equal to the angle of reflection. This means that when a ray of light strikes a surface and is reflected, the angle at which it strikes the surface (the angle of incidence) is equal to the angle at which it is reflected.

This law can be represented by the following equation:

θ_i = θ_r

Where θ_i is the angle of incidence and θ_r is the angle of reflection.

This law holds true for all types of waves, not just light waves. It is a fundamental principle of wave behavior and is essential for understanding how waves interact with surfaces.
