Which of the following graphs is the magnification of a real image against the distance from the focus of a concave mirrorr ?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
D
For concave mirrorr `m=(f)/(f-u)`
For real image `m=-(f)/((u-f))=-(f)/(x)`
`=(f)/(("Distance of object from focus"))impliesm prop (1)/(x)`
