Vedclass · Answer

(C) Step $1$: Given data:Frequency of the electromagnetic wave $f = 1 \, 	ext{kHz} = 10^3 \, 	ext{Hz}$.Velocity of the electromagnetic wave $c = 3 	imes 10^8 \, 	ext{m/s}$.Step $2$: Calculate the wavelength:The relationship between wavelength $\lambda$, velocity $c$, and frequency $f$ is given by $\lambda = \frac{c}{f}$.Substituting the values:$\lambda = \frac{3 	imes 10^8 \, 	ext{m/s}}{10^3 \, 	ext{Hz}}$$\lambda = 3 	imes 10^5 \, 	ext{m}$.Step $3$: Convert to $km$:Since $1 \, 	ext{km} = 10^3 \, 	ext{m}$, we have:$\lambda = \frac{3 	imes 10^5}{10^3} \, 	ext{km} = 300 \, 	ext{km}$.

The wavelength of an electromagnetic wave radiated by a charge oscillating with a frequency of $1 \, \text{kHz}$ is ..... $km$.
