Chapter 22, Problem 55GP

In reading the instruction manual that came with your garage-door opener, you see that the transmitter unit in your car produces a 250 mW signal and that the receiver unit is supposed to respond to a radio wave of the correct frequency if the electric field amplitude exceeds 0.10 V/m. You wonder if this is really true. To find out, you put fresh batteries in the transmitter and start walking away from your garage while opening and closing the door. Your garage door finally fails to respond when you’re 42 m away. Are the manufacturer’s claims true?
What is the maximum power level of a radio station so asto avoid electrical breakdown of air at a distance of 0.65 mfrom the transmitting antenna? Assume the antenna is apoint source. Air breaks down in an electric field of about 3 x106 v/m?
A very small source of light that radiates uniformly in all directions produces an electric field
amplitude of 8.19 V/m at a point 9.05 m from the source. What is the average power output from
the source? (Use c = 2.9979 x 108 m/s)
