WebAug 13, 2012 · Students learn the basics of the photoelectric effect and how to apply it in context to solve problems. WebHe calculated it by making the hypothesis that energy comes only in discrete packets (i.e. the photon). He uses this assumption to calculate the frequency distribution of black body radiation with his constant h being the separation between allowed frequency values and it exactly matched what was experimentally observed. 2 comments ( 40 votes)
WebSolution: Energy of the incident photon is E = hv = hc/λ (in joules) E = hc/λe (in eV) Substituting the known values, we get E = 6.626×10−34 ×3×108 / 300×10−9 ×1.6×10−19 … WebSay in a photoelectric experiment, we find a stopping potential of 1.85V for λ = 3000 A ∘ and of 0.82V for λ = 4000 A ∘. How can I get the Planck's constant from the above information? Determine the work function of the sodium in electron-volts. Determine the threshold wavelength for sodium.
