The stream of electrons from a heated filament was passed between two – InterviewSolution

1.	The stream of electrons from a heated filament was passed between two charged plates kept at a potential difference of 2 V volts. If e and m are the charge and the mass of electron respectively, then the value of hλ is: (where λ is the de Broglie wavelength of the electron)
Answer» The stream of electrons from a heated filament was passed between two charged plates kept at a potential difference of $2 V$ volts. If e and m are the charge and the mass of electron respectively, then the value of $\frac{h}{λ}$ is: (where $λ$ is the de Broglie wavelength of the electron)
