2.1 Calculate the energy equivalent of a proton mass. When a uranium-235 nucleus captures a neutron, the nucleus becomes unstable and splits into a tin nucleus and a molybde- num nucleus. This typical fission reaction is expressed as 92 U235 +on+son 124 + 42 Mo 100 +12 onl +energy. Calculate the energy released per gram of uranium. (Atomic masses of U-235, Sn-124, and Mo-100 are 235.116, 118.69, and 95.94 amu, respectively.) Visible light has a range of wavelengths from about 4,000 at the blue end to about 8,000 at the red end. What is the frequency and energy of a green photon whose wavelength is 6,000 ? What is the frequency and energy of a 0.008- gamma photon? 2.1 Calculate the energy equivalent of a proton mass.
