ELI5: What happens when you tune a radio? How do the frequencies change?

The station frequencies don't change, but by tuning you are adjusting the receive part of your radio to become sensitive to a certain frequency you want to hear. Inside the radio are parts (capacitors, inductors and resistors) that allow this resonance frequency to be set.
