A) \[\frac{{{f}^{2}}}{x+f}\]
B) \[\frac{{{f}^{2}}}{x}\]
C) \[\frac{xf}{x-f}\]
D) \[\frac{xf}{x+f}\]
E) \[\frac{{{f}^{2}}}{x-f}\]
Correct Answer: E
Solution :
\[\frac{1}{f}=\frac{1}{v}+\frac{1}{u}\] and \[m=\frac{v}{u}=-\frac{I}{O}\] Using above relation, the length of image \[I=\frac{{{f}^{2}}}{x-f}\]You need to login to perform this action.
