The Photoelectric Effect and Wave-Particle DualitySign up
understand how diffraction experiments provide evidence for the wave nature of electrons · be able to use the de Broglie equation lambda = h/p · understand that waves can be transmitted and reflected at an interface between media · understand how a pulse-echo technique can provide information about the position of an object and how the amount of information obtained may be limited by the wavelength of the radiation or by the duration of pulses · understand how the behaviour of electromagnetic radiation can be described in terms of a wave model and a photon model, and how these models developed over time · be able to use the equation E = hf, that relates the photon energy to the wave frequency · understand that the absorption of a photon can result in the emission of a photoelectron · understand the terms 'threshold frequency' and 'work function' and be able to use the equation hf = phi + 1/2 m v_max^2 · be able to use the electronvolt (eV) to express small energies · understand how the photoelectric effect provides evidence for the particle nature of electromagnetic radiation · understand atomic line spectra in terms of transitions between discrete energy levels and understand how to calculate the frequency of radiation that could be emitted or absorbed in a transition between energy levels.
