Answer:
Suppose a radio or TV station is transmitted a programme at frequency f, then waves produce alternating voltage of frequency f, in areal, due to which an emf of same frequency is induced in LC circuit, When capacitor C is in circuit is varied then for a particular value of capacitance C, f = 1/2π√(LC), the resonance ...
