Binding energy curve shows the variation of Binding energy per nucleon of nuclei with mass number.1. Binding energy per nucleon is maximum for mass number…….2. The figure shows dis integration of Deuteron.What should be the frequency of the incident photon to break Deuteron into proton and neutron?Mass of proton mp = 1,007276u.Mass of neutron mn = 1,008665uMass of deuteron = 2.013553u |

Answer» 1. 56 2. Mass defect = (1.007276 + 1.008665) – 2.013553 = 0.002388u Binding Energy = 0.002388 × 931 MeV = 2.223 MeV Energy supplied to the photon = 2.223 × 106 × 1.6 × 10-19 = 3.56 × 10-13J Frequency of photon v = \(\frac{E}{h}=\frac{3.56\times10^{-13}}{6.62\times10^{34}}\) = 5.4 x 1020Hz |
