Explanation:

Wave-Particle Duality

The interference phenomena demonstrated by the work of Young, Fresnel and others in the early 19th Century, apparently settled

the matter that light was a wave phenomenon, contrary to the views of Newton a century earlier--case closed! But nearly a century

later, phenomena were discovered which could not be satisfactorily accounted for by the wave theory, specifically blackbody

radiation and the photoelectric effect.

Deviating from the historical development, we will illustrate these effects by a modification of the double slit experiment. Let us

equip the laser source with a dimmer switch capable of reducing the light intensity by several orders of magnitude, as shown in

Figure . With each successive filter the diffraction pattern becomes dimmer and dimmer. Eventually we will begin to see

localized scintillations at random positions on an otherwise dark screen. It is an almost inescapable conclusion that these

scintillations are caused by photons, the bundles of light postulated by Planck and Einstein to explain blackbody radiation and the
