(a) A particle with mass m has kinetic energy equal to three times its rest energy. What is the de Broglie wavelength of this particle? (Hint: You must use the relativistic expressions for momen- tum and kinetic energy: E2 = (pc2) + (mc2)2 and K = E - mc2.) (b) Determine the numerical value of the kinetic energy (in MeV) and the wavelength (in meters) if the particle in part (a) is (i) an electron and (ii) a proton.
Explain – based solely on thermodynamic considerations – why the energy density of a photon cavity is proportional to T^4, independent of the size, shape and material of the cavity.
(1) For the helium-neon laser, estimate the Doppler broadening of the output wavelength 632.8 nm at T= 293 K. (2) Estimate the broadening of the same wavelength due to the Heisenberg uncertainty principle, assuming that the metastable state has a lifetime of about 1 ms.
