If A Real Image Of A Window Is Formed On A Plane White Paper Using A Concave Mirror, Then What Does The Distance Between The Mirror And The Paper Signify?

Question

If a real image of a window is formed on a plane white paper using a concave mirror, then what does the distance between the mirror and the paper signify?

Solution

Parallel rays of light coming through the window converge to create a real image at the focus of the concave mirror. Therefore, the distance between the mirror and the image cast on the paper gives the approximate focal length of the concave mirror.
