Question

In an experiment to determine the focal length of a convex lens, 1/u (cm−1) was plotted on horizontal and 1/v (cm−1) on the vertical axis, where u and v have their usual meaning. What is the physical significance of the reciprocal of the intercept on the horizontal axis?

linear magnification
focal length
object distance
image distance

Answer 1

The reciprocal of the intercept on the horizontal axis is U- object distance . So answer: object distance
