A radio broadcasts at a wavelength of $3.06 \mathrm{~m}$. Near the broadcast tower the electric-field amplitude is $2700 \mathrm{~N} / \mathrm{C}$. Calculate (a) the frequency, (b) the wave number, and (c) the magnetic-field amplitude of the electromagnetic wave.
An AM radio station broadcasts at $570 \mathrm{kHz}$. (a) What is the wavelength of the radio wave in air? (b) If a radio is tuned to this station and the inductance in the tuning circuit is $0.20 \mathrm{mH},$ what is the capacitance in the tuning circuit? (c) In the vicinity of the radio, the amplitude of the electric field is $0.80 \mathrm{V} / \mathrm{m} .$ The radio uses a coil antenna of radius $1.6 \mathrm{cm}$ with 50 turns. What is the maximum emf induced in the antenna, assuming it is oriented for best reception? Assume that the fields are sinusoidal functions of time.
A simusoidal electromagnetic wave emitted by a cellular phone has a wavelength of 35.4 $\mathrm{cm}$ and an electric-field amplitude of $5.40 \times 10^{-2} \mathrm{V} / \mathrm{m}$ at a distance of 250 $\mathrm{m}$ from the antenna. Calculate (a) the frequency of the wave; (b) the magnetic-field amplitude; (c) the intensity of the wave.
