Sample Response: Scientists believe that light is
made of streams of particles because only the presence
of photons can explain phenomena observed during
experiments on the photoelectric effect. These
observations include only some frequencies of light
causing the ejection of electrons, no time gap existing
between light striking a metal and electrons being
ejected, and intensity having no effect on the kinetic
energy of the ejected electrons.
