(A) The relationship between wavelength $(\lambda)$,frequency $(
u)$,and speed of light $(c)$ is given by $\lambda = \frac{c}{
u}$.Given:Speed of light $(c) = 3 	imes 10^8 \ m/s$Frequency $(
u) = 1368 \ kHz = 1368 	imes 10^3 \ Hz$Calculation:$\lambda = \frac{3 	imes 10^8 \ m/s}{1368 	imes 10^3 \ s^{-1}}$$\lambda = \frac{300000000}{1368000} \ m$$\lambda \approx 219.298 \ m$Rounding to one decimal place,we get $\lambda = 219.3 \ m$.

Find the wavelength of electromagnetic radiation having frequency $1368 \ kHz$. (in $m$)
