Answer 2

✓Radio broadcasts use a specific frequency of radio waves.

✓ A radio receiver uses inductors and capacitors to resonate at the same frequency in order to pick up the broadcast.

✓ Because this process is similar to tuning a musical instrument - adjusting one thing so it’s on the same frequency as a reference frequency - the process is called ‘tuning’. It usually involves variable capacitors, since variable inductors aren’t as cheap.
