![]() ![]() Regular reflection takes place, and an image is formed at point B. This makes the atoms unstable, so they tend to become stable again by reflecting those photons in the opposite direction.Īs you get to know about how many types of mirrors are there in optics, you should now also understand the detailed explanation on the important types individually.įor example, let us consider a ray of light is incident on a plane mirror at a point. In the case of an ordinary house mirror, when a ray of light falls on its surface, the silver molecules behind the glass get excited by absorbing the photons. On the other hand, a ray of light which travels from a mirror to the image, formed due to reflection, is known as a reflected ray.Īns. What is an incident ray and a reflected ray?Īns: A light ray, which travels from a source to a reflecting surface, is known as an incident ray. The features of a mirror image depend primarily on the type of mirror used.Ģ. This virtual image, thus formed, is known as a mirror image. a concave spherical mirror and a convex spherical mirror.įurthermore, this classification is explained with an illustration given below.īefore we carry on with our topic on Mirrors, brush up your memory on these essential pointers in the Q&A section discussed below.Īns: When light is incident on any type of mirror from a particular source, it is not only reflected, but it also creates a virtual image inside the reflecting surface. Moreover, spherical mirrors can be further classified into two types, i.e. ![]() Mirrors can be broadly classified as plane mirrors, rotating mirrors, inclined mirrors, and spherical mirrors. There are different types of mirrors in physics. Refracted Ray: When the incident ray passes through a second medium, it is known as a refracted ray. Normal Ray: The ray of light that is perpendicular to the reflecting surface. Reflected Ray: The ray of light that gets reflected after getting hit on the surface. Incident Ray: The ray of light that hits the surface. So, in the case of a mirror, it is a specular reflection. In the case of a rough surface, it is reflected back in all directions and this is known as diffuse reflection but for smooth surfaces, it gets reflected in one single direction and is known as specular reflection. The reason why the light gets reflected when it falls on a mirror is that at the microscopic level, it is a smooth surface. In the case of a mirror, light is always reflected. We know that the light either gets reflected or absorbed. As a matter of fact, mirrors work on the principle of reflection. When light hits a mirror surface, it reflects every colour of the spectrum. Moreover, a mirror will keep on reflecting light in a regular fashion until or unless an opaque object is introduced between the reflecting surface and the source of light. In physics, a mirror is defined as a surface that reflects nearly all kinds of light incidents on it. Moreover, the surface on which the reflection of light takes place is known as a mirror. ![]() So, the phenomenon due to which illumination takes place on a diffused or polished surface is known as a regular reflection of light. Meanwhile, a polished surface will tend to appear illuminated only in one direction for a given position of an observer. When a light source illuminates a perfectly diffused surface, it usually appears bright in all directions. ![]()
