A radio wave is transmitting with a power per unit area ofI=196W/m².

Randomized VariablesI =196 W/m²

25%Part (a)A surface area absorbs the wave completely. Express the radiation pressure on the surface,P_a, in terms ofIand the speed of lightc.

P_a=

25%Part (b)Solve for the numerical value ofP_ain N/m². 25%Part (c)A surface area reflects the wave completely. Express the radiation pressure on the surfaceP_a, in terms ofIandc. 25%Part (d)Solve for the numerical value ofP_a.
