In Figure an isotropic point source of light S is positioned at distance d from a viewing
Question:
In Figure an isotropic point source of light S is positioned at distance d from a viewing screen A and the light intensity Ip at point P (level with S) is measured. Then a plane mirror M is placed behind S at distance d. By how much is Ip multiplied by the presence of the mirror?
