About this audiobook
Why does a metal bathed in bright red light throw off no electrons, while a feeble violet beam makes them leap instantly? This book tells the story of the photoelectric effect, the small, stubborn observation that forced physics to accept that light delivers its energy in indivisible packets. It follows Heinrich Hertz, who found the effect by accident in 1887 while proving that light was a wave; Wilhelm Hallwachs and Aleksandr Stoletov, who made the first quantitative laws; and Philipp Lenard, whose discovery that electron energy ignores brightness broke the classical picture beyond repair. It explains Einstein's 1905 light quanta in plain words, and Millikan's reluctant decade of measurement that confirmed the theory, measured Planck's constant, and won both of them Nobel Prizes.
