The uncertainly in position for an electron is `(lamda)/(4 pi)` where `lamda` is the de Broglie wavelength. The uncertainly in velocity will be -

The de-Broglie wavelength lamda

If uncertainly in position and momentum are equal then uncertainty in velocity is

When uncertainty in position and momentum are equal, then the uncertainly in velocity is

If the de broglie wavelength of an electron is 1Å, then the velocity of the electron will be

Electrons are emitted from the cathode of a photocell of negligible work function, when photons of wavelength lamda are incident on it. Derive the expression for the de Broglie wavelength of the electrons emitted in terms of the wavelength of the incident light
