Question

If the distance between an object and a plane mirror is 1.5 metres, what will be the distance between an image and the object in a plane mirror?​

Answer 1

In a plane mirror,the distance between an object and a plane mirror is equal to the distance between an image and the  plane mirror.

So, the distance between the image and the plane mirror would also be 1.5m

And the distance between the object and the image would be 1.5 + 1.5 = 3 m
