Physics

The average intensity of a particular TV station

Answer & Explanation Solved by verified expert
4.4 Ratings (586 Votes)

The intensity of the signal, I = 3.0 * 10-13 W/m2

The Diameter, D = 70 cm = 0.77 m

So radius, r = 0.385 m

Area, A = ?r2 = 0.4657 m2

Power, P = IA = 0.4657*3 * 10-13 = 1.3971*10^-13 W

a)

Time, t = 7 hours = 14400 s

Energy = power * time = 2.012 * 10-9 J

b) The amplitude of electric field is

             Emax = ?[2c?o I]

                      = ?[2(3.0 x10^8 m/s)(4? x 10^-7 H/m)(3.0 x10^-13 W/m2)]

                      = 1.504 x10^-5 V/m

The amplitude of magnetic field is

           Bmax = Emax/c

                     = ( 1.504 x10^-5 V/m)/(3.0 x10^8 m/s)

                     = 5.013 x10^-14 T
