Why is it necessary to tune the oscillating circuit to the frequency of the transmitting station?

The radio airwaves are full of electromagnetic waves from hundreds of thousands of radio stations and interference sources that emit radio waves at various frequencies.

In this chaos, the oscillating circuit serves as a filter. It, tuned to one frequency, enters into resonance with the electromagnetic oscillations of the radio station transmitter, and suppresses unnecessary radiation at other frequencies.

So, with the help of an oscillatory circuit, it is possible to hear a radio station without interference from other sources of radio waves.
