1. In the Bohr model of the atom, the energy of the electron depends only on one quantum number, n. In the Paschen series of the spectral wavelengths, the electronic transitions always terminate at the n=3 level.
a. Calculate the energy of the electron in the n=3 level of hydrogen, in electron volts.
b. What is the smallest possible 'energy gap" between the n=3 level and some other level/ Given the answer in electron volts.
c. What is the longest wavelength of light given off in the Paschen series of hydrogen?
2. Why was the Bohr model unsatisfactory in giving us a compete model for atoms?
a. How long (as observed by someone on earth) will it take Spiff to travel from the earth to Mars?
b. What is the distance Spiff measures for the distance from the earth to Mars?
Solution attaches a Word file to show how to answer these 5 multi-part questions covering distances and travel times from Earth to Mars, atom model physics and electron energies.
