[solved]-The Wavelength Of An Electron Beam Is Measured To Be 900 0 Nm What Is The Veloci

The wavelength of an electron beam is measured to be 900.0 nm . What is the velocity of the electrons?

In the same beam, the uncertainty in the momentum is 6.626 * 10‒25 kg m/s. (the uncertainty in the beam’s wavelength is ± 0.5 nm) What is the minimum uncertainty in the position of the electron?
