Vedclass · Answer

(A) According to the de Broglie equation,the wavelength $\lambda$ is given by $\lambda = \frac{h}{mv}$.The distance traveled by the electron in one second is equal to its velocity,$v$ (since $d = v 	imes t$ and $t = 1 \ s$).Given that the wavelength is equal to the distance traveled in one second,we have $\lambda = v$.Substituting this into the de Broglie equation: $v = \frac{h}{mv}$.Rearranging the equation: $v^2 = \frac{h}{m}$.Therefore,the velocity is $v = \sqrt{\frac{h}{m}}$.
