A particle with mass 2.2  10 −31 kg has a de Broglie wavelength of 112 Å . Determine the momentum and kinetic energy of the particle.

De Broglie postulated that the relationship ? = h/p  is valid for relativistic particles. What is the de Broglie wavelength for a (relativistic) electron having a kinetic energy of 3.18 MeV?

In an experiment to study the photo-electric effect, light of wavelength 400 nm shining on a metallic surface causes electrons to be emitted. The maximum kinetic energy of the electrons is 1.05 eV (electron volts). Another light source of wavelength 200 nm is then tried, and the emitted electrons have a maximum kinetic energy of 4.20 eV. Using this information: a) determine the value of Planck's constant. b) determine the work function of the metal.
