Nb: mark values are given in brackets [ ] beside each problem. Write all your answers on the quiz paper. Energy levels of h atom: en = 13. 6 ev/n2. 1 m2 ) de broglie relation: = h/p. Speed of light c = 3. 00 108 m/sec. Planck"s constant h = 6. 626 10 34 j-sec. Rydberg constant r = 1. 097 107 m 1. Mass of electron me = 9. 11 10 31 kg. Mass of proton (or neutron) mp = 1. 67 10 27 kg. 1 m ev = 1. 6 10 13j and. Suppose now that the proton is in the third excited state: sketch the proton"s wavefunction. Where inside the well/box will the particle never be found: suppose you measure the particle"s position. [4] suppose a 60-w light-bulb converts 6. 2% of its input energy into visible light of wavelength 580 nm. How many (visible) photons per second does the bulb emit? (1 w =
