The magnificationof the image when an object is placed at a distance x from the principle focus of a mirror of focal length f is

A

`(x)/(f)`

B

`1+(f)/(x)`

C

`(f)/(x)`

D

`1-(f)/(x)`

Text Solution

Verified by Experts

The correct Answer is:
C
We know that, magnification
`m=(f)/(f-u)`
`u=f+x impliesm=(-f)/(x)implies|m|=(f)/(x)`
