Image Formation in Plane Mirror

Q. Fig. 16.10 shows the word REST written in two ways in front of a mirror. Show how the word would appear in the mirror.

R \( E \) \( S \) R E S T \( T \) Fig. \( 16.10 \)

Q. In the image formed by a plane mirror the left of the object appears on the right and the right appears on the left, this is known as:
