What would be the work function of a metal that could produce photoelectrons from the peak wavelength of the Earth's blackbody radiation at this temperature? What would be the kinetic company chose to base its operations in Death Valley, California, whose summers see a surface energy of a photoelectron produced by light half this wavelength?arrow_forwardGamma rays (?-rays) are high-energy photons. In a certain nuclear reaction, a ?-ray of energy 0.836 MeV (million electronvolts) is produced. Compute the frequency of such a photon.

Two of your friends are arguing over the cause of the sparking, with one stating that the microwaves "herd" electrons into "pointy" areas of the metal object, from which the electrons jump from one part of the object to another. The other friend says that the sparks are caused by the photoelectric effect. Prove or disprove the latter idea using basic physics. Suppose the typical work function of the metal is roughly 3.630 × 10-19 J. Calculate the maximum wavelength in angstroms of the radiation that will eject electrons from the metal. wavelength: Åarrow_forward
