Vedclass · Answer

(D) According to the de-Broglie equation: $\lambda = \frac{h}{mv}$.Given that the wavelength $(\lambda)$ is equal to the distance travelled by the electron in one second, we have $\lambda = v 	imes 1 = v$.Substituting $\lambda = v$ into the de-Broglie equation: $v = \frac{h}{mv}$.Rearranging the terms: $v^2 = \frac{h}{m}$, which gives $v = \sqrt{\frac{h}{m}}$.Since $\lambda = v$, we get $\lambda = \sqrt{\frac{h}{m}}$.Thus, the correct relation is $\lambda = \sqrt{\frac{h}{m}}$.

Which of the following relations is correct, if the wavelength $(\lambda)$ is equal to the distance travelled by the electron in one second? $h$ is the Planck's constant and $m$ is the mass of electron.
