Vedclass · Answer

(B) The relationship between frequency $
u$,speed of light $c$,and wavelength $\lambda$ is given by the formula: $
u = \frac{c}{\lambda}$.Given: $c = 3 	imes 10^8\,m/s$ and $\lambda = 1\,\mathring{A} = 1 	imes 10^{-10}\,m$.Substituting these values into the formula:$
u = \frac{3 	imes 10^8}{1 	imes 10^{-10}} = 3 	imes 10^{18}\,Hz$.Therefore,the correct option is $B$.

$X$-rays of wavelength $\lambda = 1\,\mathring{A}$ have a frequency of:
