Explain the Feynman diagram for the exchange of a virtual photon between two positive charges.
Use Wien’s law to answer the following questions: (a) The cosmic background radiation peaks in intensity at a wavelength of 1.1 mm. To what temperature does this correspond? (b) About 379 000 y after the big bang, the universe became transparent to electromagnetic radiation. Its temperature then was 2970 K.What was the wavelength at which the background radiation was then most intense?
Consider the case where an electron and a positron annihilate each other and produce photons. Assume that these two particles collide head-on with equal, but slow, speeds. Is it possible that only one photon is produced? If yes, how? If not, is it possible that only two photons are produced? If yes, how? Is it possible that the produced photons have different energies? Explain your reasoning based on the conservation laws of physics.
