Learning Goal: To understand the experiment that led to the discovery of the photoelectric effect. In 1887, Heinrich Hertz investigated the phenomenon of light striking a metal surface, causing the ejection of electrons from the metal. The classical theory of f electromagnetism predicted that the energy of of the electrons ejected should the have been proportional to the i I to the intensity of the light. However, Hertz observed that the energy of the electrons was independent of the intensity of the light. Furthermore, for low enough frequencies, no electrons were ejected, no matter how great the intensity of the light became. The following problem outlines the methods used to investigate this new finding in physics: the photoelectric effect. Submit Request Answer Part D In a 1905 paper that later won him a Nobel Prize, Albert Einstein postulated that the energy of light was proportional to its frequency. The constant of proportionality turned out to be Planck's constant h: Elight = hf. Using your previous results, and the equation given in Part C, find an expression for h in terms of experimentally determinable quantities. Express your answer in terms of the slope m and e. 15.

Learning Goal: To understand de Broglie waves and the calculation of wave properties. In 1924, Louis de Broglie postulated that particles such as electrons and protons might exhibit wavelike properties. His thinking was guided by the notion that light has both wave and particle characteristics, so he postulated that particles such as electrons and protons would obey the same wavelength-momentum relation as that obeyed by light: \ =h/p, where X is the wavelength, p the momentum, and h Planck's constant.
