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 like

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
D
For a lens `(1)/(f)=(1)/(v)-(1)/(u)`
If `u=oo, v=f` and if `u=f, v=oo`

Three students measured the focal length of a convex lens using parallel rays from a distant object. All of the measured the distance between the lens and the inverted image on the screen. (i) Student A saw a sharp image on the screen and labelled the distance as f_(1) (ii) Student B saw a slightly larger blurred image on the screen and labelled the distance as f_(2) (iii) Student C saw slightly smaller blurred image on the screen and labelled the distance as f_(3) The relation between the three measurements would most likely be :
