Images Formation by Plane Mirrors
Plane mirror reflects a replica of the object placed in front of them. When a light coming from an object falls on a plane mirror it bounce back or get reflected in the same medium at an angle equal to the angle of incidence. The reflected rays meet virtually or appears to meet behind the mirror forming an image of the object.
- The ray of light that falls on the reflecting surface from the object or a source is known as an incident ray.
- The ray of light that is supposed to be reflected after striking the reflecting surface is known as the reflected ray.
The characteristics of the image formed by plane mirror is discussed below:
Characteristics of Image Formed by Plane Mirror
The characteristics of the image formed by the plane mirror is mentioned below:
- The image formed through the plane mirror is always virtual (the image that cannot be obtained on-screen) and erect (Upright or straight).
- The size of the object and the size of the image are equal.
- The distance the object is placed is the same as the distance between the image obtained.
- Laterally inverted images, i.e., the object’s right side appears on the left side behind the mirror, are obtained.
Plane Mirror
A plane mirror is a type of mirror that has a flat, reflective surface. It reflects light rays in a predictable manner. Plane mirror is generally used as dressing mirror. It forms a virtual and erect image. The size of the image is formed is same as that of object. In this article, we will learn in detail about the plane mirror, image formation by plane mirrors and its characteristics. We will also learn about the applications of plane mirror and compare it with spherical mirror, parabolic mirror and elliptical mirror.
