Vedclass · Answer

(B) The relationship between the speed of light $(c)$,frequency $(f)$,and wavelength $(\lambda)$ is given by the formula: $\lambda = \frac{c}{f}$.Given: $c = 3 	imes 10^8 \ m/s = 3 	imes 10^{10} \ cm/s$ and $f = 8.196 	imes 10^6 \ Hz$.Substituting the values into the formula:$\lambda = \frac{3 	imes 10^{10}}{8.196 	imes 10^6} \ cm$.$\lambda = \frac{3}{8.196} 	imes 10^4 \ cm$.$\lambda \approx 0.36603 	imes 10^4 \ cm$.$\lambda \approx 3660 \ cm$.Thus,the wavelength is $3660 \ cm$.

Electromagnetic waves of frequency $8.196 \times 10^6 \ Hz$ are propagating from a source. What is the wavelength of these electromagnetic waves in $cm$?
