Question

Explain the reason for getting an virtual and upright image in a plane mirror.

Answer 1

It is due to the lateral inversion of the plane mirrors and also the shape of it as it is plane shiny and smooth and even its transparentancy.So it has a virtual and an upright image.

Answer 2

The correct Answer is regular reflection.

Explanation:

Regular reflection of light occurs from smooth surfaces like mirror.

When parallel beam of light falls on the smooth surface of a plane mirror, it is reflected as a parallel beam in only one direction thus, a plane mirror produces regular reflection of light.

In regular reflection of light, all the particles of a smooth surface like plane mirror are facing in one direction
Due to this the angle of incidence for all the parallel rays of light falling on smooth surface is the same and hence the angle of reflection for all the rays of light is also the same.

Plane mirror produces virtual image means it cannot be captured on the screen but can only be seen in mirror.
Virtual Image is produced when the reflected light rays appears to converge at a point.
Plane mirror produces erect image means upright that is top of object will be top of image. Bottom of object will be bottom of image.
Magnification of plane mirror = +1
Means produces virtual , erect and same image size as object.
