What is the maximum wavelength shift Δλ = Blank 1. Calculate the answer by read surrounding text. fm for a Compton collision between a photon that travels at a speed of 254214189.33m/s and a free proton with mass 1.69E-27kg? [NOTE: Units of wavelength shift must be femtometer (fm). Enter only a numerical answer in two decimals on a space provided.]
7.129 A technique called photoelectron spectroscopy is usedto measure the ionization energy of atoms. A gaseoussample is irradiated with UV light, and electrons areejected from the valence shell. The kinetic energies ofthe ejected electrons are measured. Because the energyof the UV photon and the kinetic energy of the ejectedelectron are known, we can write where ν is the frequency of the UV light, and m and uare the mass and velocity of the electron, respectively.In one experiment the kinetic energy of the ejectedelectron from potassium is found to be 5.34 × 10−19 Jusing a UV source of wavelength 162 nm. Calculate theionization energy of potassium. How can you be surethat this ionization energy corresponds to the electron inthe valence shell (i.e., the most loosely held electron)?
