PPT-Young’s Double-Slit Experiment

Pg 477 484 Interference We now know that the experiments failed for two simple but important reasons 1 Atoms send out a burst of light energy about every 10 8 s so the probability that the atoms in each source would emit their light waves in phase is nearly zero the result is an interference pattern that changes in an irregular fashion and is impossible to see. ’. s Experiment. 2.
