Radio waves if your favorite fm radio station broadcasts at a frequency of 104.5 mhz, what is the wavelength of the station’s signal in meters? what is the energy of a photon of the station’s electromagnetic signal?

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.

the first step is making objective observations.

they have to be based on a certain event and can be confirmed by others if it is right or not.
