Vedclass · Answer

(C) According to the de Broglie relation,the wavelength $(\lambda)$ of a moving particle is given by: $\lambda = \frac{h}{mv}$Here,$h$ is Planck's constant,$m$ is the mass of the electron,and $v$ is its velocity.Since $\lambda \propto \frac{1}{v}$,the wavelength is inversely proportional to the velocity of the electron.Therefore,as the velocity $(v)$ of the electron increases,its wavelength $(\lambda)$ decreases.
