Problem: 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.

FREE Expert Solution

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:


E=hv


where:

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.

  • The conversion factors are: 

1 kHz = 10-3 Hz

1 Hz = 1 s-1
