Two vertical parallel mirrors A and B are separated by 10 cm. A point object O is placed at a distance of 2 cm from mirror A. The distance of the second nearest image behind mirror A from the mirror A is _______ cm.

 

Question diagram: Two vertical parallel mirrors A and B are separated by 10 cm
Answer:
18.00
Solution:

As can be seen from the image above, object distance is 8 cm [For image by B]

In a plane mirror the image distance is equal to the object distance. Thus, the required distance is

8+8+2 cm=18 cm
