Answer:
The wavelength of the station’s signal is 2.9 meters
The energy of a photon of the station’s electromagnetic signal is
Explanation:
Wavelength is inversely proprtional to frequency (f) and directly proportional to velocity of the wave (v).
(1)
But electromagnetic waves as radio signals travel at speed of light so using this on (1):
Albert Einstein discovered that energy of electromagnetic waves was quantized in small discrete packages of energy called photons with energy:
with h the Planck's constant.
