Vedclass · Answer

(C) The frequency of the signal is $f = 1000 	ext{ kHz} = 10^6 	ext{ Hz}$.The speed of electromagnetic waves in free space is $c = 3 	imes 10^8 	ext{ m/s}$.The wavelength $\lambda$ is given by $\lambda = \frac{c}{f} = \frac{3 	imes 10^8}{10^6} = 300 	ext{ m}$.For effective transmission, the minimum length of the antenna should be $\frac{\lambda}{4}$.Therefore, the minimum length $L = \frac{300}{4} = 75 	ext{ m}$.

For transmitting a signal of frequency $1000 \text{ kHz}$, the minimum length of the antenna is (in $\text{ m}$)
