Calculate the wavelength of light emitted when an electron falls from the 96 orbit of the hydrogen atom. Such species are known as high Rydberg atoms. They are detected in astronomy and are more and more studied in the 3. n=97 orbit to the n = laboratory.
Express the speed of the electron in the Bohr model in terms of the fundamental constants (me, e, h, 0), the nuclear charge and the quantum number n. Evaluate the speed of an electron in the ground states of He+ ion and U91+. Compare these speeds with the speed of light c. As the speed of an object approaches the speed of light, relativistic effects become important. In which kinds of atoms do you expect relativistic effects to be greatest?
