Question

wave -transformer С. distant field Energy source transmission line R L( Oscillator

What is the wavelength (in vacuum) of the electromagnetic wave emitted by the oscillator-antenna system in the figure above if L = 0.25 μH and C = 40 pF?

Answer 1

Fequency of LC Oscillator is given by, $f = \frac{1}{2 \pi \sqrt{LC}} = \frac{1}{2 \pi \sqrt{0.25 * 10^{-6}*40*10^{-12}}} = 5.03 * 10^7 Hz$

Wavelength is given by, $\lambda = \frac{c}{f} = \frac{3* 10^8}{5.03*10^7} = 5.96 m$
