Question
$\because$ As you drive by an AM radio station, you notice a sign sayingthat its antenna is 112 $\mathrm{m}$ high. If this height represents one quarter-wavelength of its signal, what is the frequency of the station?
Step 1
So, the wavelength of the signal is four times the height of the antenna. That is, \[\lambda = 4 \times 112 \, \text{m}.\] Show more…

As you drive by an AM radio station, you notice a sign saying that its antenna is $112 \mathrm{m}$ high. If this height represents one quarter-wavelength of its signal, what is the frequency of the station?
The antenna for an AM radio station is a 77.5 m high tower whose height is equal to one-quarter the wavelength of the broadcast signal. At what frequency does the station transmit? Number: Hz
The antenna for an AM radio station is a 75 -m-high tower whose height is equivalent to one-quarter wavelength. At what frequency does the station transmit? Example $22-1$
