In an experiment to measure1 the focal length f of a converging lens object distances u and corresponding image distance were measured and 1/u plotted against 1/v to obtain the graph illustrated. How would f be determined from this graph?
-
A.
f= the slope of the graph -
B.
f= the intercept on the 1/u axis -
C.
f =the intercept on the 1/v axis -
D.
f = reciprocal of the slope -
E.
f = reciprocal of the intercept on either axes
