At what frequency does the radio station operate if the wavelength of the radio transmitter is 50 m.

Electromagnetic waves propagate at the speed of light c. If we divide the distance traveled per unit of time (speed) by the wavelength L, we get the number of oscillations per second (frequency f):
f = c / L = (3 * 10 ^ 8 m / s) / 50 m = 6 * 10 ^ 6 Hz.
Answer: 6 * 10 ^ 6 Hz (6 MHz).

One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
