The magnification of an image formed by a pin hole camera is 0.0005. If the object is at a distance of 500 m, calculate the distance of image from the pinhole.

Answer:

\[m=0.0005\] object distance, \[u=500\text{ }m\] Image distance, \[v=?\] We know that, \[m=\frac{v}{u}\Rightarrow v=mu\] \[\Rightarrow \]\[v=0.0005\times 500=0.25m\]
