a. Figure (a) shows the optical axis of a lens, the point source of light A, and its virtual image `A^(')` . Trace the rays to find the position of the lens and of its focuses. What type of lens is it?

b. Solve the problem similar to the previous one using Figure.

Text Solution

Verified by Experts

The correct Answer is:
