1.	Does a pencil appear to be displaced to the same extend, if insted of water? Explain.
Answer» A pencil dipped in water appears to be bent at the interface of air and water due to the refraction of light. The refraction of light occurs because the speed of light changes when light travels from one medium to another. Therefore, the pencil will not appear to be bent to the same extent, when it is dipped in kerosene or turpentine. This is because refractive index of kerosene or turpentine is different than the refractive index of water and hence speed of light will be different in kerosene than that in water.
