Suppose Raghu has kept an object in front of a concave mirror of focal length (f) at various distances (u) and he has measured the corresponding image distances (v). From such an experiment, Raghu is able to plot a graph of u against 1/magnification, i.e. u vs 1/m. Which of the following options is true?
A.
It is a straight line with slope +f, and x intercept +1 and y intercept –f
B.
It is a straight line with slope –1/f, and x intercept +1 and y intercept –f
C.
It is a straight line with slope 1/f, and x intercept –1 and y intercept +f
D.
It is a straight line with slope +f, and x intercept –1 and y intercept +f
