What is the wavelength of a radio photon from an "am" radio station that broadcasts at 1500 kilohertz?

Respuesta :

Answer;

Wavelength = 200 m

Explanation;

wavelength = wave speed / frequency.  

Speed = 3x10^8 m/s

frequency = 1500x10^3 Hz

In this case;

Wavelength = 3x10^8 m/s / 1500x10^3 s^-1

                    = 200 m.
