Homework Answers
A)
Magnetic field, B = E/c
B = (0.37 x 10^-6)/(3 x 10^8)
B = 1.23 x 10^-15 T
B)
Intensity, I = 0.5 μo(EB)
I = (0.37 x 10^-6)(1.23 x 10^-15)/2(4π x 10^-7)
I = 1.82 x 10^-16 W/m^2
C)
Power, P = IA
P = (1.82 x 10^-16) pi x 5.45^2
P = 1.70 x 10^-14 W

This question has several parts that must be comple ted sequentially. If you skip a part of the question, you will not receive any points for the skipped part, and you will not be able to come back to the skipped part.

Assume i wanted to increase the detection range of my phone with a dish antenna. A 3m-diameter parabolic dish is readily available commercially, and the desired sinusoidal radio signal specification is for Emax = 0.10 µV/m. Assume the antenna absorbs all the radiation that is captured by the dish (100% efficiency): (a) (10) What is the amplitude of the magnetic field in this signal?

Question1. A U.S. or Canadian broadcasting licence for a (large) FM radio station stipulates a maximum broadcast power of 100 kW. At any distance from the broadcast antenna the intensity doesn’t quite follow the inverse square law that is described for spherical waves in the videos lectures, because of reflection of the signal off of the ground. But the inverse square law is not a bad approximation, so let’s use it a) Find the intensity of the radio signal from...

A radio station transmits isotropically (i.e. in all directions) electromagnetic radiation at the frequency of 98.2 MHz. At a certain distance from the radial station the wave intensity is I = 0.295 W / m ^ 2. a) What will be the intensity of the wave three times the distance of the radial station? b) What is the wavelength of the transmitted signal. c) If the antenna power is 6 MW. At what distance from the source will the wave...
