Q.7 (a) If the wavelength of an electron is 100 nm, what is its speed? (b) The kinetic energy of an electron in an atom, such as hydrogen, is typically around 10eV. What is the wavelength of an electron with this energy? (c) How does this wavelength compare with the size of a hydrogen atom? (d) For an electron that is confined within a hydrogen atom, what is the minimum possible uncertainty in its momentum?
