Question

 I am standing at some distance away from a plane mirror such that the distance between me and my image is 6m. Now if I start moving with a speed of 1 m/s towards the mirror, what will be the new position of my image after 1 second?​

Answer 1

Answer:

In a plane mirror if the mirror moves at speed of v, then the image moves at a speed of 2v.

So, in this case, as mirror is moving at a speed 10 cm/s, the image will move at a speed of (2)×(10)cm/s =20cm/s
