Question

The figure represented below shows the word REST which has been written in two ways in front of a mirror. Indicate how the word would appear in the mirror.

Answer 1

Hint: Lateral inversion is defined as the process produced by a plane mirror in the reversing of images from left to right. A lateral inversion that is the left side of the body will appear on the right side of the image and the right side of the body will appear on the left side of the image. This will help you in answering this question.

Complete step by step answer:
 In the case of a plane mirror the image produced will undergo a lateral inversion that is the left side of the body will appear on the right side of the image and the right side of the body will appear on the left side of the image. Also, the image will be formed at the equal distance behind the mirror as the body is being kept in front of it. By considering the above two rules in mind the figures which are showing the images produced by the word REST can be written in two ways in front of the mirror as represented below.

Note: A plane mirror is defined as a kind of mirror which has a flat and planar reflective surface. In the case of light rays incident on a plane mirror, the angle of reflection will be equivalent to the angle of incidence. The angle of the incidence will be the angle between the incident ray and the normal drawn to the surface which is a hypothetical line perpendicular to the surface. Hence, the angle of reflection will be the angle between the reflected ray and the normal and except for the diffraction effects, the light beam will not spread out after the reflection from a plane mirror.
