A 2 cm diameter coin rests flat on the bottom of a bowl in which the water is 20 cm deep `(mu_(w) = 4//3)`. If the coin is viewed directly from above, what is its apparent diameter ?

An object lies 100 cm inside water (mu=4//3) . It is viewed from air nearly normally. Find the apparent depth of the object.

An object lies 100 cm inside water (mu=4//3) . It is viewed from air nearly normally. Find the apparent depth of the object.

A 20 mm thick layer of water (mu=(4)/(3)) floats on a 35 mm thick layer of another liquid (mu=(7)/(5)) in a tank. A small coin lies at the bottom of the tank. Determine the apparent depth of the coin when viewed normally from above the water.

If a fish lies at the bottom of a 4 m deep water tank (mu = 4//3) and a bird is flying at a height of 6m above the water surface, then apparent distance at which the fish appears to the bird is

A metal coin at the bottom of a beaker filled with a liquid of refractive index 4//3 to height of 6 cm . To an observer looking from above the surface of the liquid, coin will appear at a depth of (consider paraxial rays).

A metal coin at the bottom of a beaker filled with a liquid of refractive index 4//3 to height of 6 cm . To an observer looking from above the surface of the liquid, coin will appear at a depth of (consider paraxial rays).

A coin is placed at the bottom of a beaker containing water (refractive index=4/3) at a depth of 12cm. By what height the coin appears to be raised when seen from vertical above ?

A convex lens is held directly above a con lying on a table and forms an image of it. After the lens has been moved vertically a distance equal to its focal length, it forms another image of the coin equal in size with the previous image. If the diameter of the coin is 16 mm, what is the diameter in milimeters of the image?
