Question

an insect is sitting at a distance of 80 cm in front of a plane mirror.if it moves 0.20m towards the mirror what will be the distance of the insect from its image now​

Answer 1

Answer:

In a plane mirror, object distance = image distance.

The initial object distance is 80 cm.

The insect moves 0.20 m towards the mirror.

so the final object distance = 80 - 0.20 m.

0.20 m into cm = 20 cm.

final object distance = 80 - 20 cm = 60 cm or 0.60 m.
