Question
What is the ratio of the wavelength of a $0.100-\mathrm{keV}$ photon to the wavelength of a $0.100-\mathrm{keV}$ electron?
Step 1
100-keV photon and a 0.100-keV electron. We can use the energy-wavelength relationship for photons: E = hc/λ, where E is the energy, h is the Planck's constant (6.626 x 10^-34 Js), c is the speed of light (3 x 10^8 m/s), and λ is the wavelength. For a 0.100-keV Show more…
