Learning outcomes - after studying this topic, you should be able to:

• calculate the energy of a photon from its wavelength, and its wavelength from its energy
• relate absorption and emission of photons to changes in electron energy levels
• calculate energy levels for one-electron atoms
• calculate the momentum of particle from its wavelength and calculate the wavelength of a particle from its momentum
