Question

An object is at a distance of 15.2m in front of a plane mirror. If it moves 4.9m towards the
mirror. What is the distance between its object and its image?​

Answer 1

Answer:

20.6 m

Explanation:

object distance=15.2 m

•°• Image distance is also equal to 15.4 m(since it is a plane mirror)

Object is moved 4.9 m towards the mirror

•°• Object Distance 2 = 15.2-4.9

= 10.3 m

•°• Image distance 2 is also equal to 10.3

Therefore distance between Object and Image = 10.3+10.3=20.6 m
