Reflection Of Light In Plane Mirrors

Characteristics of images formed by plane mirror.

Reflection of light in plane mirrors. The process of sending back the light waves after falling on the surface of an object is called a reflection of light. There are rules for obtaining images from plane mirror. Images formed by a plane mirror are of same shape and size as that of an object. Consider a plane mirror and a fixed incident ray of light reflecting from the surface at an angle θ i.

The angle of the incidence is the angle between the incident ray and the surface normal an imaginary line perpendicular to the surface. The path of light is always a straight line and this single beam of light is called a ray of light.

Before the mirror has rotated the angle of incidence is θ as is the angle of reflection. Solved example for you. Images formed by a plane mirror are of same shape and size as that of an object. Images formed by a plane mirror are always virtual.

Images formed by a plane mirror are erect upright. Learn more about the laws of reflection of light in detail. Images formed by a plane mirror are always virtual. Through this experiment you will learn about the reflection from a plane mirror.

If the mirror is rotated through an angle φ the normal is rotated by an angle phi and thus the angle of incidence increases to θ φ. For light rays striking a plane mirror the angle of reflection equals the angle of incidence. Therefore the angle of reflection is the angle between the reflected ray and the normal and a. Images formed by a plane mirror are erect upright.

The law of reflection can be used to understand the images produced by plane and curved mirrors. A plane mirror is a mirror with a flat reflective surface. The reflection of an object over a plane mirror forms images at many different places. Reflection is the bouncing of light off the surface that it strikes on.

Reflection of light is the process of sending back the light rays which fall on the surface of an object. Reflection is the bending of light off the surface that it strikes on.
