Two plane mirrors of length are separated by distance and a man is standing at distance from the connecting line of mirrors as shown in figure. A man is walking in a straight line at distance parallel to mirrors at speed , then man at O will be able to see image of for total time:
Options:
Answer:
C
Solution:
Image of the path of is a line behind the mirrors, so from O.
Edges of each mirror are at and from the axis, at distance from O .
On the image line (distance ) these scale by to , a length .
Two mirrors give total length .
