Vedclass · Answer

(A) In the Davisson and Germer experiment,the electron gun accelerates electrons using an electric potential $V$. The kinetic energy $K$ gained by an electron of charge $e$ and mass $m$ is given by $K = eV = \frac{1}{2}mv^2$. Solving for velocity $v$,we get $v = \sqrt{\frac{2eV}{m}}$. From this relation,it is clear that the velocity $v$ is directly proportional to the square root of the accelerating potential difference $V$. Therefore,the velocity of the electrons can be increased by increasing the potential difference between the anode and the filament.

In the Davisson and Germer experiment,the velocity of electrons emitted from the electron gun can be increased by
