Which of the following is correct graph between u and v for a concave mirror for normal sign convention?

Answer:

Solution:

For a concave mirror $\frac{1}{v} + \frac{1}{u} = \frac{1}{f}$ with the normal sign convention, so the u-v relation is a rectangular hyperbola.

For a real object the real-image branch lies with both u and v negative, matching graph (B).

Answer: B
