| Law of Reflection | | | We use plane mirrors to show the image through reflection of light. If we use a block of glass, there would be reflection as well as refraction. This would distort the image and is undesirable. Also on all glass surfaces, there will always be less reflection and more refraction. More over for a certain thickness of glass there may not be any reflection at all. To avoid all these problems, plane mirrors are made out of thin glass plates to reflect the light and display our image. Most plane mirrors have a coating of silver to increase their reflection. | | Previous | Next |
