A sample of hydrogen atoms is irradiated with light with a wavelength of 89.0 nm, and electrons are observed leaving the gas. If each hydrogen atom were initially in its ground level, what would be the maximum kinetic energy in electron volts of these photoelectrons? A few electrons are detected with energies as much as 10.2 eV greater than the maximum kinetic energy calculated in part A. How can this be?

Please help me out with this questions. Thank you.
Neutrons can be produced at low temperatures to serve as probes of molecular structure. When the de Broglie wavelength of a neutron is on the order of the dimensions of chemical bond lengths, the diffraction patterns are especially important for molecular structure. If the speed of a thermal neutron is given by the expression v = (3k_BT/m)^1/2, at what temperature will neutrons have a de Broglie wavelength of 50 pm =...

2) Consider a stellar atmosphere composed of pure helium. You will find the temperature at the middle of the He I partial ionization zone, where half of the He I atoms have been ionized. (Such an atmosphere would be found on a white dwarf of spectral type DB.) The ionization energies of neutral helium and singly ionized helium are Eion-24.6 ev and Eion-54.4 ev, respectively....

4.8 He-Ne Laser The He-Ne laser system energy levels can be quite complicated, as shown in Figure 4.58. There are a number of lasing emissions in the laser output in the red (632.8 nm), green (543.5 nm), orange (612 nm), yellow (594.1 nm), and in the infrared regions at 1.52 μm and 3.39 μm, which give the He-Ne laser its versatility. The pumping mechanism for all these lasers operations is the same, energy transfer from excited He atoms to Ne...
