Review Packet_ Midterm 1 .pdf Download Review Packet Midterm 1.pdf (241 KB) accurate mass of 1 ug? What is the wavelength of the small particle? Calculate the energy of a photon (m = 0 kg, A = 6.000 × 107 m, c = 2.998 x 10° m/s), a neutron (m = 1.674 x 10-27 kg, v = 2200 m/s, A = 1.799 × 10-10 m), and 2.000 moles of neutrons (travelling at the same speed as the single %3D %3D neutron). A bar of hot metal is emitting blackbody radiation. The peak wavelength of this radiation is orange. If the photons at this wavelength have an energy of 3.30 x 10-10nJ each, what is the temperature of the metal? Given that 390.0nm of light is able to eject an electron at 200.0km/s from the surface of a metal, what is the work function of of the metal?
