A radio can tune over the frequency range or a portion of {MW}

Question

Question asked by Filo student

A radio can tune over the frequency range or a portion of $MW$ broadcast bond; $(800 kHz$ to $1200 kHz$ ). If its LC circuit has an effective inductance of $220 μ H$ , what must be the range of its variable capacitor? [Hint: For tuning the natural frequency i.e, the frequency of free oscillations of the LC circuit should be equal to the frequency of the radiowave.]
