Air Force, facing fighter pilot shortage, offers retention bonuses of up to $225,000. The Air Force estimates that without a serious recruiting effort, it will be short 700 fighter pilots eight years from now -- so it is offering retention bonuses of up to $225,000 to stay in the service for an additional nine years. The deadline to respond to this unusual help wanted ad is Sept 30.
A community for students. Which energy transition may take place in the atom if its electron has absorbed a photon? A.n = 5 to n = 1 B.n = 3 to n = 2 C.n = 5 to n = 2 D.n = 1 to n = 3 E.n = 3 to n = 1 Help me!!! if the electron ABSORBS a photon, that means it must GAIN energy. when electrons RELEASE photons, they drop in energy, which is why we see colors in an emission test.
l = hc/E. A photon with an energy of 10.2 eV has a wavelength of 1.21 x 10-7 m, in the ultraviolet part of the spectrum. So when an electron wants to jump from n = 1 to n = 2, it must absorb a photon of ultraviolet light. When an electron drops from n = 2 to n = 1, it emits a photon of ultraviolet light.
