Dec 28, 2020 · The law of reflection states that the angle of incidence equals the angle of reflection, measured relative to the normal line of a reflective surface. This simple rule describes many phenomena, from the diffuse reflection of the sun on the sea to the crisp reflection of your face in a mirror.
What Is Law of Reflection? Definition: The law of reflection defines that upon reflection from a smooth surface, the angle of the reflected ray is equal to the angle of the incident ray, with respect to the normal to the surface that is to a line perpendicular to the surface at the point of contact.

If a ray of light could be observed approaching and reflecting off of a flat mirror, then the behavior of the light as it reflects would follow a predictable law known as the law of reflection. The diagram below illustrates the law of reflection.

The mirror-like reflection of light rays is known as a specular or regular reflection of light. The light will reflect at the same angle from a smooth, shining surface, such as glass, water, or polished metal. This sort of reflection of light is produced by plane mirrors with a smooth surface. In this case, the image is distinct and clearly visible...
A type of light reflection that is not mirror-like is called diffused or irregular reflection of light. Rays of light that are reflected off of a rough surface scatter in all directions. Because most natural surfaces are rough on the scale of the wavelength of light,parallel incident light rays are irregularly or diffusely reflected in many distinc...
Mirrors and other such reflecting surfaces are excellent at maintaining the intensity of light in a reflection. Because of this, multiple reflections can be produced from a single light source by using this type of reflecting surface. These multiple reflections are achievable up until the point at which the light is so weak that we cannot see it. A...
Jun 9, 2019 · Reflection of Light occurs when a ray of light approaches a smooth surface and bounces back. The laws of reflection determine the reflection of incident light rays on reflecting surfaces. Know more at BYJU'S.

The law of reflection states that the angle of reflection equals the angle of incidence— . The angles are measured relative to the perpendicular to the surface at the point where the ray strikes the surface. Light is diffused when it reflects from a rough surface.
