Photoelectric effect �1887: Heinrich Hertz: � In experiments on e.m. waves, unexpected new observation: when receiver spark gap is shielded from light of transmitter spark, the maximum spark-length became smaller � Further investigation showed: o Glass effectively shielded the spark o Quartz did not o Use of quartz prism to break up light into wavelength components ⇒ find that wavelength which makes little spark more powerful was in the UV 6
Hertz and p.e. p.e. effect o Hertz’ conclusion: “I confine myself at present to communicating the results obtained, without attempting any <strong>theory</strong> respecting the manner in which the observed phenomena are brought about” 7
