Consider the situation shown in figure. A plane mirror is fixed at a height h above the bottom of a beaker containing water (refractive index `mu`) up of a bottom formed by the mirror.

Text Solution

Verified by Experts


Distance of image of O from water surface `=d/mu`
Distance of I from mirror`=h-d+d/mu`
Image of I i.e. `I^'` is formed at distance `=h-d+d/mu` above/ behind the mirror.

Consider the situation in figure. The bottom of the pot is reflecting plane mirror , S is small fish is a human eye . Refractive index of water is mu . Fish can see two images of human eye , first due to refractive only and other due to refraction and than reflection . Distance of these images from fish are S_(1) "and" S_(2) respectively . Human eye can also see the two images of fish, first due to refraction only and other due to reflection and then refraction . Distance of these images from human eye are S_(3) "and" S_(4) respectively .
