the wavelengths For the firet three lines in the stre series for hydrogen. ? (a) ,ind eutaerneguoney for the photoelectrie effect is illleon, (b) Find the maximum energy of the cjected electrons if the silicen is illuminated widh light of frequency 2.7 x10* H 3, An electron drogs Find (a) the energy and (b) the wavelength of the photon emitted. om the n.. 8 to the n-2level or an infinite square well as am wide 4 Determine the principal and orbital quantum numbers for a hydrogen atom whose electron has energy-1.SI eV and orbital angular momentum L-V20n. 5. what wavelength ofradiation is needed to excite a transition between the n-1, 1-i state and the ?-2,2-0 state in diatomic deuterium (D), for which the rotational inertia is 9.17 x 104 kg-m' and the classical vibration frequency is 93.5 THz? 6. The mass of a nitrogen-14 nucleus is 14.003074 u. Find the binding energy per nucleon. 7. Analysis ofa Moon rock shows that 43% of its initia! U-238 has decayed to Pb 206, a process with a half-life of4.46 × 10, years. How old is the rock? 8. A so-called kaonic atom is a hydrogen atom with the electron replaced by a kaon; the kaon's nass is 966 times the electron's. Find (a) the size and (b) ground state energy of a kaonic atom. However, since the kaon is a hadron, not a lepton, it's actually more complicated. us problem (worth 5 points of extra credit): beta particle (mass 0.00055 u) is trapped in a cesium nucleus with diameter 12 fm. ng they system as a one-dimensional square well, what would be the minimum energy fo a particle?
