in this class we are going to discuss Gate physics 2018 Q.no 22.
A light beam of intensity is falling normally on a surface. The surface absorbs 20% of the intensity and the rest is reflected. The radiation pressure on the surface is given by X 1₁/c, where X is (up to one decimal place). Here c is the speed of light.
