When a pencil is partly immersed in water in a glass tumbler, why does it appear to be displaced at the interface of air and water? Does a pencil appear to be displaced to the same extent, if instead of water, we use liquids like kerosene or turpentine?

Solution

Dear Student,
the displacement is due to the refraction light. thats depend upon the refractive index of the liquid . since the refractive index of water is hgher then bend of the pencil will be larger and for the kerosene oil the displacment is less as the refractive index of the kerosene is lesser than the water. so it totally depends upon the refractive index of the liquid.
