Rays of light from the beam of an oncoming car hit this smooth surface, undergo specular reflection and remain concentrated in a beam. The driver perceives an annoying glare caused by this concentrated beam of reflected light. A second application of the distinction between diffuse and specular reflection pertains to the field of photography.

- Law of Reflection
Specular reflection, or regular reflection, is the mirror-like reflection of waves, such as light, from a surface. [ 1 ] The law of reflection states that a reflected ray of light emerges from the reflecting surface at the same angle to the surface normal as the incident ray, but on the opposing side of the surface normal in the plane formed by the incident and reflected rays.
The law of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection. Reflection and the Locating of Images It is common to observe this law at work in a Physics lab such as the one described in the previous part of Lesson 1 .

Incident Ray:The ray of light that is incident on the interface.Reflected Ray:The ray of light that is reflected from the interface.Normal:The perpendicular to the interface.Angle of Incidence:The angle that the incident ray makes with the normal.In the case of specular reflection, the angle of reflection is equal to the angle of incidence, thus giving a mirror-like reflection.
In the case of diffuse reflection, the incident ray reflects from the interface in all directions. In other words, the angles of reflections are different for each reflected ray.
We know that light is a form of energy which can undergo various phenomena like refraction, reflection, diffraction, and interference. In this session, let us know more about the laws of reflection (first law of reflection and second law of reflection), types of reflection, examples, differences, and total internal reflection.

Mar 23, 2022 · The law of reflection states that the angles of an incident ray and reflected ray are the same as each other and are in the same plane as the normal. The law describes the behavior of light reflecting off of a very smooth surface. This is specular reflection or regular reflection. In contrast, diffuse reflection occurs from an irregular surface ...

The angles are measured with respect to the normal. These laws apply to all types of reflection, whether the surface is smooth (leading to specular or regular reflection) or rough (leading to diffuse or scattered reflection). Regular reflection occurs when light rays reflect off a smooth surface and remain parallel, creating a clear image.
