A light wave of a particular frequency hits a metal. The light wave is made of discrete photons, each with energy hf = hc/λ. An electron will either completely absorb a photon, or not at all. An electron in a metal needs an energy to leave the metal -- the work function (W). For the W given, calculate the maximum light wavelength (in nm) that will eject an electron. I will use electron-volts (eV) for energy, because the computer gives me trouble with very low numbers. hc = 1240 eV nm W = 3.9 eV
In designing an experiment, you want a beam of photons and a beam of electrons with thesame wavelength of 0.281 nm, equal to the separation of the Na and Cl ions in a crystal ofNaCl. Find the energy of the photons and the kinetic energy of the electrons in electrovolts(eV).
In an x-ray tube, the maximum photon energy is given by hf = qV. Would it be technically more correct to say hf = qV + BE, where BE is the binding energy of electrons in the target anode? Why isn’t the energy stated the latter way?
Molybdenum has a work function of 4.20 eV. What is the stopping potential if the incident light has a wavelength of 180 nm?
In a photoelectric effect experiment using UV light of wavelength 100 nm, a stopping voltage of V = 7.68 V is found. (a) Find the work function of the metal used. Using an appropriate table of work functions (in your text, for example), identify the metal. (b) Will there be a photoelectric effect using light of wavelength 200 nm? If so, find the stopping voltage. (c) Will there be a photoelectric effect using light of wavelength 400 nm? If so, find the stopping voltage.
For x rays with wavelength 0.0300 nm, the m = 1 inten- sity maximum for a crystal occurs when the angle u in Fig. is 35.8°. At what angle u does the m = 1 maximum occur when a beam of 4.50 keV electrons is used instead? Assume that the electrons also scat- ter from the atoms in the surface plane of this same crystal.
Based on your answer in Question 7, when light with a wavelength of 198 nm strikes the surface of tin metal, electrons are ejected with a maximum kinetic energy of 2.9 x 10-19 J. What is the binding energy of these electrons to the metal?
