In an experiment to find focal length of a concave mirror, a graph is drawn between the magnitude of u and v. The graph looks like:
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
In case of a concave mirror, when we move the object from infinity to focus of the mirror, (i.e. u decreases from 
to f), the image moves from focus to 
(i.e. v increases from f to 
). Therefore, the graph looks like the curve shown in .
