Unformatted text preview: F . It is very useful to know that hc = 197MeV fm. (d) Evaluate the speed of the neutron (or proton) in the Bohr orbit, relative to the speed of light. (e) In the rst Bohr orbit it still must be that the total energy (sum of kinetic and potential energy) is negative , to achieve a bound state. This puts a constraint on r ; nd and evaluate that constraint. (f) For the numbers in this problem, numerically evaluate the potential energy near r = 0, and compare your result with page 95 of the text. 2. Consider the photon emitted when a hydrogen atom goes from the n = 100 Bohr orbit to the n = 1 Bohr orbit. Derive an expression for the ratio of the wavelength of the photon to the Bohr radius, and evaluate numerically. 3. Anderson, 213 4. Anderson, 215 5. Anderson, 218 6. Anderson, 221...
