Bohr model has electrons doing what around nucleuis? orbiting Wavelength of light: larger = (energy) lower Unit of measuring Frequency Hertz Frequency of light: larger = (energy) higher Meaning of λ wavelength Meaning of v with a line on it Frequency Meaning of c speed of light λ is equal to what c/v Meaning of h planck's constant Meaning of E energy E is equal to what hv Experiment that shows wave description of light double slit Energy is made of packets called `name` name: quanta Red has `adj` energy, purple has `adj2` energy adj: less adj2: more Lowest energy state of atom? ground state Higher energy state of atom? excited state When atoms go into higher energy state they `action`, makes `type` spectrum action: absorb light type: absorbtion When atoms go into lower energy state (which they do after going into higher energy state) they `action`, makes `type` spectrum action: emit light type: emission Theory of light? particle-wave duality
