A water pond appears to be 2.7 m deep. If the refractive index of water is 43, find the actual depth of the pond.
Water in a pond appears to be only three-quarter of its actual depth. (a) What property of light is responsible for this observation? Illustrate your answer with the help of a ray diagram. (b) How the refractive index of water calculated from its real and apparent depths?
A coin is placed at the bottom of a 3 cm deep pond. The refractive index of water is 1.5. At what depth does the coin appear to be, as seen from above the pond?
