Answer:
The pencil appears to be bent when it is kept in a glass tumbler with water due to refraction of light. The refraction of light occurs when the speed of light changes when it travels from one medium to another.But when the pencil is dipped in kerosene or in oil, the bending is not the same because they are optically denser than water.
The pencil appears to be bent when it is kept in a glass tumbler with water due to refraction of light.When a ray of light travels from a rarer mediun to a denser medium it bends towards the normal . Thus tye pencil appears bent. The refraction of light occurs when the speed of light changes when it travels from one medium to another But when the pencil dipped in kerosene or in oil, the bending is not the same because they are optically denser than water.
If pencil is kept inside turpentine or kerosene the bending is not the same as water since its less dense than water.
