Question:

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

Options:

increasing the potential difference between the anode and filament

increasing the filament current

decreasing the filament current

decreasing the potential difference between the anode and filament

Correct Answer:

increasing the potential difference between the anode and filament

Explanation:

when the potential increases, the Potential difference between the electrodes increase and the flow of electrons also increases.
