Question

A radio wave is transmitting with a power per unit area of I = 105 W/m^2.

 

Part (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.

 

P(a) =

 

 

Part (b) Solve for the numerical value

of P(a) in N/m^2.

 

P(a) =

 

 

Part (c)  A surface area reflects the wave completely.  Express the radiation pressure on the surface P(a) , in terms of I and c.

 

P(a) =

 

 

Part (d) Solve for the numerical value of P(a).

 

 

P(a) =
