Problem
Two separate series circuits P and Q each contain a capacitor of 50nF. Circuit P uses a 2.0mH inductor, whereas circuit Q uses a 0.50mH inductor.
(i) Calculate the resonant frequency of each circuit.
(ii) Find the ratio fQ:fP.
(iii) For the circuit that resonates at the higher frequency, determine the wavelength of an electromagnetic wave in air having that frequency (take speed of light =3.0×108ms−1).
