Document Summary
Bohr atom in 1913, planetary model quantized emission transitions came from electrons jumping btwn different orbits n = 3 n = 2 n = 1. +ze this is actually wrong b/c electrons are wavelike quantized orbits. Bohr"s idea = to quantize angular momentum n = 1,2,3 solve for r --> find fixed set of quantized orbits electron can move about only in circular orits w/ radii given by r! -> can correct: replace me with reduced mass, mu constant = 109676 cm-1. What is the radius of the first bohr orbit? (n = 1) for n = 2, it is 4 time a0 memorize bohr radius. Quick recap invoking concept of quantization, researchers around 1900 were able to explain many strange results blackbody radiation: quantize light --> planck derived eqn to explain observed experimental emission spectra. Use those formulas to calculate t of emitting objects. Photoelectric effect: einstein quantized light into discrete packets, explain all expt observables.
