You are working in an x-ray laboratory. You have a source of x-rays with a wavelength of 0.115 nm. In the experiment you are performing, you need x-rays with a slightly longer wavelength than this. You decide to use Compton scattering from electrons to increase the wavelength of the x-rays. For theexperiment, you need to determine (a) at what angle x-rays with a wavelength 1.2% larger than those from your source will be scattered. (b) You also need to determine the longest possible wavelength you can achieve with Compton scattering.
Fresh out of university you've been hired to do some photoelectron spectroscopy. You have a lamp that outputs an unknown wavelength of light. When the light is incident on a metal with a work function of 6.31 eV, you observe a stopping voltage equal to 4.21 V. What is the wavelength of the light? (unit in nm).
