A convex mirror of focal length 'f' is placed at the origin with its reflecting surface towards the negative x-axis . Choose the correct graps between 'v' and 'u' for u`lt 0`.

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
C

As convex mirror is placed at origin & reflecting surface towards -ve x-axis.
For u`gt 0 implies` Real objects.
For all cases of real objects, the image formation towards right of the origin v is +ve and also between pole & focus.
