Question

02. An object is approaching a plane mirror at 10cm-s'. A stationary observer sees
the image. At what speed will the image approuch the stationary observer?
​

Answer 1

Answer:

10 cm-s' will be the answer according to image rules

Answer 2

Explanation:

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
