An antenna with power P $=2\mathrm{.}8103$ W is radiating spherical electromagnetic waves. Consider a place which is d $=145$ m away from the antenna.

Randomized Variables

P $=2\mathrm{.}8103$ W

d $=145$ m

Part $($a$)$

Express the average intensity of the wave, I, in terms of P and d$.$

I $=$

$$ Part $($b$)$

Express I in terms of the electric field magnitude Emax, the speed of light c$,$ and the permeability of free space $0.$

$$ Part $($c$)$

Find Emax$2$ in terms of P$,$ d$,$ c$,$ and $0.$

$$ Part $($d$)$

Solve for the numerical value of Emax in volts per meter.
