Document Summary
Slide 14: light interacts with matter, the more photons the brighter the light, light = wave. Slide 16: anything with temp is giving off light. Also a black body: as you cool from sun temp to earth. Keep the same shape but diminish intensity, wavelength to longer. Slide 17: old theory: up and up no max, rst inkling that something new had to be proposed. Slide1 9: 3rd problem, rydberg eqn where lines would be (?) Friday, september 29, 2017: jj thompson, localized - charge, plums are e, positive parts delocalized, e repelling each other. 21: ernest r nucleus localized, everything would be attracted and clash. 22: niels bohr world orbital adopted but no one thought that it was like planets, spinning and charged, math is like orbitals. 23: moving ups nd down between orbits corresponds between spectral lines, cannot be in between, e levels are obey perfectly.
