Document Summary

Tro chapter 7 notes textbook/ true false questions probability of finding electrons with specific nrg in specific region of atom. Interference pattern of dark (destructive- wvlth/2 path) and light (constructive, equal path) film describes wave bc inherent ability to diffract through slits. Photoelectric effect can"t be waves bc then changing wavelength or amplitude of wave (color or intensity) would affect rate of electron emission from metals. But it didn"t!! omg fuck now we gotta figure this shit out must be particulate in nature as well. Classical prediction: expected brighter light to increase, dim to decrease (amplitude) But results: high frequency, low intensity (dim) dislodged electrons. Also noticed threshold frequency (low doesn"t eject, high does) So depends of frequency, not amp or wavelength. Ugh yuck. b/c increasing intensity only increases number of low nrg photons, not their frequency. Increasing frqcy increasing nrg (direct relationship, rmbr??) shorter the wavelength, the more nrg the photon has, therefore greater.
