1.	A student measures the focal length of a convex lens by putting an object pin at a distance `u` from the lens and measuring the distance `v` of the image pin. The graph between `u` and `v` plotted by the student should look likeA. B. C. D.
Answer» Correct Answer - 2 For real image u is (-)and v is (+)and`(1)/(v)-(1)/(u)=(1)/(f)`constant
