... Many people are aware that Einstein was awarded the Nobel Prize in Physics in 1921 for his work on the photoelectric effect in 1905, but fewer people are aware of the work that preceded his explanation. In 1887, Heinrich Hertz first observed the photoelectric effect when investigating “spark gap” ra ...

10.2 Diffraction Notes
... • Destructive interference is difficult to accomplish since most natural sources of light are incoherent which means they emit light waves randomly. • It is much easier to observe light if the phases of the waves have a fixed pattern. This is called coherent. ...
