      nature. We shall try to understand in this Chapter the reflection of light by spherical mirrors and refraction of light and their application in real life situations. 10.1 REFLECTION OF LIGHT A highly polished surface, such as a mirror, reflects most of the light falling on it. You are already familiar with the laws of reflection of light.

      normal line). Also note the slight reflection from the front of the block. As the light leaves on the other side of the plastic block it bends away from the normal line. The amount of refractive bending of the light caused by the plastic block is an intrinsic property of the material making up the block itself.

      The speed and the wavelength of incident light changes on entering from one medium to another medium. This results in the change in the direction of the light. 3. Does reflection take place along with refraction? Ans. Yes, a small amount of light gets reflected at the surface of separation of two media. 4. State two laws of refraction.
