X-rays with a wavelength of 0.0045 nm are used in a Compton scattering experiment. If the X-rays are scattered through an angle of 45o, what is the wavelength of the scattered radiation?
Answer to relevant QuestionsA photon with an energy of 5.0 keV is scattered by a free electron. (a) The recoiling electron could have an energy of (1) zero, (2) less than 5.0 keV, but not zero, (3) 5.0 keV. Why? (b) If the wavelength of the scattered ...Find the radius of the electron orbit in a hydrogen atom for states with the following principal quantum numbers: (a) n = 2, (b) n = 4, (c) n = 5. A hydrogen atom in its ground state is excited to the n = 5 level. It then makes a transition directly to the n = 2 level before returning to the ground state. (a) What are the wavelengths of the emitted photons? (b) Would ...Show that the orbital speeds of an electron in the Bohr orbits are given (to two significant figures) by vn = (2.2 x 106 m/s/n). What is the minimum energy of a thermal oscillator in a blackbody producing radiation at λmax at a temperature of 212oF?
