Document Summary

2: vmin for a given metal; kinetic energy of electrons increases as v (frequency) increases); current increases as light intensity increases, einstein: 1 photon extracts 1 electron. Energy of a photon: hv = ei (metal) + ek (e-: light is a stream of photons; mass less energy quantity (wave and/or photons) 2 ev hv: photochemical reactions: i(cid:374)du(cid:272)ed (cid:271)y light, photo(cid:374)s as (cid:862)(cid:396)ea(cid:272)ta(cid:374)ts(cid:863) (cid:894)hv) (as flux of photons) 2 hcl + 2 h etc exothermic chain reactions in upper atmosphere. H: rh=2. 179 x 10-18 j, energy different decreases as the number of the energy levels increases (recall the diagrams, ground state: lowest allowed energy, exited state: when an e- gains a quantum of energy. Emin = e3 - e2 = rh(1/4 - 1/9) 4: fundamental error or the bohr model was to constrain an electron to a one-dimensional orbit (the electron cannot move off a circular path of fixed radius), schr dinger:
