- 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 electromagnetism predicted that the PORA that the energy of the electrons ejected should have be have been proportional to the intensity of the light. However, Hertz observed that the energy of the dont of the interio electrons was independent the intensity of the from 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. Part B Suppose that the light carries energy Elight.

- If a red light matches the cut-off frequency of a metal and can liberate electrons from the metal surface. When a blue light shincs on the same metal, will you expect to observe the photoelectric effect (liberation of free electrons from metal) with this blue light? A. No, because blue light photon has lower energy due to smaller wavelength compared with the red-light photon. B. Yes, because blue light photon has higher energy due to higher frequency compared with the red light photon. C. Cannot be determined without additional information.arrow_forwardThe photoelectric effect is the emission of electrons from a metal when light falls on it. The maximum kinetic energy of the electrons is the photon energy less the work function of the metal. A counter-electrode placed near the surface can pick up the photoelectric current. a) The work function of copper is 4.65 eV. Calculate the maximum kinetic energy in eV of the electrons if a copper surface is illuminated with 200 nm UV light b) If the counter-electrode is charged to +10 V, what will be the maximum kinetic energy of electrons arriving on it? What negative voltage would cut the photocurrent to zero?arrow_forward3. Dimensional analysis can provide insight into Stefan-Boltzmann's law for the radiation from a black body. According to this law the intensity of radiation, in units of J s-' m-², from a body at temperature Tis 1 = GT*, where e is Stefan-Boltzmann's constant. Because black-body radiation can be considered to be a gas of photons, i.e. quantum particles which move with velocity e with typical energies of the order of kT, the intensity I is a function of h, c and kT. Use dimensional analysis to confirm that Iis proportional to 7 and find the dependence of a on h and c.arrow_forward
