Introduction to Reflection

The balancing of light from a surface is called reflection.OrThe to and fro movement of light in the same medium after striking an opaque surface is called reflection.The amount of light that is reflected depends on the material and nature of the surface on which light falls An opaque body absorbs some of the light that falls on it and reflects the remaining light. A transparent body allows almost all the light to pass through it and reflects very little light. A smooth and a highly polished surface such as a shiny stainless steel surface or a mirror reflect almost all the light that falls on it.
