We’re being asked to calculate the energy of the photons emitted by the AM radio station.
Recall that the energy of a photon (E) is given by:
h = Planck’s constant (6.626 × 10–34 J • s)
v = frequency (in s–1)
First, let’s convert the frequency in kHz to s-1 to be able to cancel out units.
1 kHz = 10-3 Hz
1 Hz = 1 s-1
An AM radio station broadcasts at 1030 kHz , and its FM partner broadcasts at 98.4 MHz .
Calculate the energy of the photons emitted by the AM radio station.
