A square mnqp is kept between F and C on the principal axis of a concave mirror as shown in figure . Find a rough image of this object.The focal length of mirror is 30cm & distance of object is 40cm.

A

120cm

B

100cm

C

80cm

D

140cm

Text Solution

Verified by Experts

Object is placed between F and C. Therefore ,image is real inverted magnified and beyond C. Further pq is towards F. Therefore ,its image p'q' is towards imfinity and it is more magnified. A rough image is as shown alongside.

From the ray shown in figure ,we can see that n'q' will be a straight line.
