Question

A radio wave is transmitting with a power per unit area of I =118 W/m².

a. A surface area absorbs the wave completely. Express the radiation pressure on the surface, P_a, in terms of I and the speed of light c.

Part (b) Solve for the numerical value of P, in N/m2.
а
Part (c) A surface area reflects the wave completely. Express the radiation pressure on the surface Pa, in terms of I and c.
Part (d) Solve for the numerical value of Pa.

Definition Definition Rate at which light travels, measured in a vacuum. The speed of light is a universal physical constant used in many areas of physics, most commonly denoted by the letter c . The value of the speed of light c = 299,792,458 m/s, but for most of the calculations, the value of the speed of light is approximated as c = 3 x 10 8 m/s.
