Question

An object is at the distance 25cm in front of a plane mirror. The mirror is shifted 5cm away from the object. Find (i) the new distance between the object and it's image. (ii) the distance between the two positions of the image

Answer 1

Answer:

In this case, the mirror is moved 25 cm away from its initial position. Therefore, if the mirror is moved with distance x, then image in the mirror will move by distance 2x.

That is, 2x=50 cm.

So, the image will shift by 50 cm away from its previous position
