At what frequency of oscillation does the radio transmitter emit electromagnetic waves with a length of 3000 m?

These tasks: λ (length of electromagnetic waves emitted by the used radio transmitter) = 300 m.

Constants: С (speed of electromagnetic waves, speed of light) = 3 * 10 ^ 8 m / s.

To determine the required frequency of oscillations of electromagnetic waves, we apply the formula: ν = С / λ.

Let’s calculate: ν = 3 * 10 ^ 8/300 = 1 * 10 ^ 6 Hz (1 MHz).

Answer: The oscillation frequency of the transmitter used will be 1 MHz.
