Vedclass · Answer

(B) Given: Frequency $(
u) = 4 	imes 10^{11} \ kHz = 4 	imes 10^{14} \ Hz$ (or $s^{-1}$).Speed of light $(c) = 3 	imes 10^8 \ m \ s^{-1}$.We know the relation: $
u = \frac{c}{\lambda}$.Therefore,wavelength $(\lambda) = \frac{c}{
u}$.$\lambda = \frac{3 	imes 10^8 \ m \ s^{-1}}{4 	imes 10^{14} \ s^{-1}}$.$\lambda = 0.75 	imes 10^{-6} \ m = 7.5 	imes 10^{-7} \ m$.

Find the wavelength of radiation having frequency $4 \times 10^{11} \ kHz$.
