Problem
In a certain tuning circuit the inductance is fixed at 0.20H. The circuit must resonate at 800Hz.
(i) Determine the capacitance that must be connected in series with the inductor to achieve this resonant frequency.
(ii) An electromagnetic wave of this frequency is emitted. Calculate the wavelength of the wave in free space, assuming the speed of light is 3.0×108ms−1. Express your answer to two significant figures.
