The graph between `(1)/(v)` and `(1)/(u)` for a concave mirror looks like.

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
B
`(1)/(v) + (1)/(u) = (1)/(f)`
Therefore, for a given mirror `(1)/(v)` versus `(1)/(u)` graph should be a straight line at `u = f` or `(1)/(u) = (1)/(f), v = oo` or `(1)/(v) = 0` and viceverse
