- In a photoelectric effect experiment, you shine light of wavelength 420 nm on a piece of sodium metal and measure the stopping potential to be 0.65 V. You then use a different spectral line with a wavelength of 310 nm and measure the stopping potential to be 1.69 V. Using those two data points, the speed of light and the elemental electric charge, find the work function of sodium and a value for Plank’s constant.In a photoelectric effect experiment you illuminate a metal with light of wavelength 290 nm and measure a stopping potential of 1.2 V. What is the work function of the metal, in electron volts?Plz don't use chat gpt Chatgpt means downvote
- Molybdenum has a work function of 4.20 eV. What is the stopping potential if the incident light has a wavelength of 180 nm?Please asapFor 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.
- For crystal diffraction experiments, wavelengths on the order of 0.25 nm are often appropriate. Find the energy in electron volts for a particle with this wavelength if the particle is (a) a photon; and (b) an electron.An electron is confined between two perfectly reflecting walls separated by the distance 10 x 10-11m. Use the Heisenberg uncertainty relation δp δx~hbar to estimate the lowest energy that the particle can have (in eV). (You will need to think about the momentum uncertainty associated with a position uncertainty)What wavelength of light is shining on a metal with work function ?=2.8??, if the stopping potential for the photocurrent (ejected electrons) is 5??
