Question

An image of a pencil is formed by a plane mirror at a distance of 40 cm from the pencil. The pencil is moved 5 cm
towards the mirror.
What will be the new image distance from the mirror? ​

Answer 1

Answer:An image of am object is observed on a plane mirror. The distance between the mirror and the imageis15cm. If the pencil is moved 3cm towards the mirror then what would be the distance between image and the objects

Explanation:

In the first condition the distance was 15 cm.

Now, the distance is decreasd from 3 cm.

So, 15-3 = 12cm.

Now the distance b/w the object and mirror is 12 cm

Hence the distance between object and image will be 12 + 12 = 24 cm

Answer 2
