A real image of an object is formed by a conex lens at the bottom of an empty beaker. The beaker is now filled with a liquid of refractive index 1.4 to a depth of 7 cm. In order to get the image again at the bottom the beaker shoud be moved

An object is placed at the bottom of a tank filled with liquid of refractive index 1.6. If the actual depth of the tank is 10 cm, what will be the apparent depth of the object?

The apparent depth of an object at the bottom of tank filled with a liquid of refractive index 1.3 is 7.7 cm. what is the actual depth of the liquid in the tank ?

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 placed at the bottom of a beaker appears to be raised by 4.0 cm. If the refractive index of water is 4/3, find the depth of the water in the beaker.

A convex lens is held 45 cm above the bottom of an empty tank. The image of a point at the bottom of a tank is formed 36 cm above the lens. Now, a liquid is poured into the tank to a depth of 40 cm. It is found that the distance of the image of the same point on the bottom of the tank is 48 cm above the lens. Find the refractive index of the liquid.
