a. A negatively charged electroscope can be discharged by shining an ultraviolet light on it. How does this happen?
b. You might think that an ultraviolet light shining on an initially uncharged electroscope would cause the electroscope to become positively charged as photoelectrons are emitted. In fact, ultraviolet light has no noticeable effect on an uncharged electroscope. Why not?
What is the length of a one-dimensional box in which an electron in the state has the same energy as a photon with a wavelength of ?
In the following Figure is an energy-level diagram for a simple atom. What wavelengths, in nm, appear in the atom鈥檚 (a) emission spectrum and (b) absorption spectrum?
Compton scattering is relevant not only to -ray photons but, even more so, to higher energy gamma-ray photons. Suppose a gamma-ray photon backscatter (i.e., is scattered back toward the source) from a free electron. Afterward, what is the electron鈥檚 velocity in ?
Calculate all the wavelengths of visible light in the emission spectrum of the hydrogen atom.
