Question

8. Rohan is observing his image in a plane mirror. The distance between the mirror and his image is
4 m. If he moves 1 m towards the mirror, find the distance between the image and the mirror?​

Answer 1

Answer:

Distance between the mirror and the image is 4m

Hence distance between Rohan and the mirror is also 4 m.

In plane mirror, object distance = image distance. (1).

Rohan moves 1 metre towards the mirror.

Distance between the object and the mirror = 4-1 = 3m

From the above (1) equation,

Image distance = 3m.
