Reflection Of Light In Plane Mirrors

A ray of light strikes a reflective plane surface at an angle of 42 o with the surface.

Reflection of light in plane mirrors.

Reflection is the absorbing of light off the surface that it strikes on. The law of reflection can be used to understand the images produced by plane and curved mirrors. 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. Through this experiment you will learn about the reflection from a plane mirror.

Solved example for you. The process of sending back the light waves after falling on the surface of an object is called a reflection of light. Reflection is the bouncing of light off the surface that it strikes on. Consider a plane mirror and a fixed incident ray of light reflecting from the surface at an angle θ i.

Therefore the angle of reflection is the angle between the reflected ray and the normal and a. Solved example for you q. Characteristics of images formed by plane mirror. Unlike mirrors most natural surfaces are rough on the scale of the wavelength of light and as a consequence parallel incident light rays are reflected in many different directions or diffusely.

The reflection of an object over a plane mirror forms images at many different places. The angle of the incidence is the angle between the incident ray and the surface normal an imaginary line perpendicular to the surface. Images formed by a plane mirror are erect upright. Images formed by a plane mirror are of same shape and size as that of an object.

Before the mirror has rotated the angle of incidence is θ as is the angle of reflection. Images formed by a plane mirror are always virtual. Images formed by a plane mirror are of same shape and size as that of an object. A plane mirror is a mirror with a flat reflective surface.

Reflection of light is the process of sending back the light rays which fall on the surface of an object. The path of light is always a straight line and this single beam of light is called a ray of light.
