Question

An object placed 5 metres from a plane mirror is shifted by 1 metre away from the mirror . What is the new distance between the object and its image? ​

Answer 1

Answer:

distance b/w object and image is 5 m

so distance of mirror from object and image is 2.5 m

if object is moved one metre away from mirror then object distance from mirror=3.5 m

distance of object from mirror=distance of image from mirror=3.5 m

distance between object and image = 3.5+3.5=7 metres answer
