A jar `15 cm` long is filled with a transparent liquid. When viewed from the top, its bottom appears to be `12 cm` below. What is the refractive index of the liquid ?

The apparent depth of a liquid in a vessel is 15 cm, when its real depth is 20 cm. find the refractive index of the liquid.

A metal plate is lying at the bottom of a tank full of a transparent liquid. Height of tank is 100 cm but the plate appears to be at 45 cm above bottom. The rerfractive index of liquid is

A tank of height 50 m is filled with oil fully. If the bottom of the tank appears to be 40 m below its top, the refractive index of the oil should be

If a light ray incidence on a liquid from air at 45^@ and get deviated due to refraction 15^@ . What is the refractive index of the liquid?

A glass lens of refractive index 1.45 disappears when immersed in a liquid. What is the value of refractive index of the liquid ?

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.
