Explanation 1) Concept: We know that energy density is intensity of e.m radiation divided by speed of light and radiation pressure also has unit of energy density. So both these physical quantities can be used to prove the required statement. 2) Formula: i) Radiation pressure for perfect reflection, P r = 2 I 0 c ii) Radiation pressure for total absorption, P a = I 0 c iii) Intensity of radiation incident on the surface of surface area A for time t I = u A t iv) Energy density of radiation with intensity I u = I c 3) Given: A plane electromagnetic wave is normally incident on a flat surface. 4) Calculations: Let I 0 be the intensity of incident radiation. Let f be the fraction of radiation reflected from the surface and ( 1 - f ) be the fraction of radiation absorbed. Then radiation pressure due to reflected radiation beam will be P r = 2 I 0 c × f Similarly, the radiation pressure due to absorbed radiation beam will be P a = I 0 c × ( 1 - f ) Therefore, the total pressure on the surface is the sum of P r and P a . P t o t a l = P r + P a = 2 I 0 c × f + I 0 c × ( 1 - f ) Taking I 0 c common from expression, we get P t o t a l = P r + P a = I 0 c ċ 2 f + 1 - f = 1 + f I 0 c Now imagine a cylinder of length l and cross sectional area A
