The graph between the lateral magnification `(m)` produced by a lens and the distance of the image `(v)` is given by

Options

A.
B.
C.
D.

Answer

C

Explanation

`(1)/(v)-(1)/(u)=(1)/(f)implies(v)/(v)-(v)/(u)=(v)/(f)`
`(v)/(u)=1-(v)/(f)impliesm=-(v)/(f)+1`
`y=-(1)/(f)x1`, comparing with `y=Mx+C`
Slope `-=(-1)/(f),C=+1`
