    Hertz wireless experiments (1887): Heinrich Hertz demonstrates free space electromagnetic waves, predicted by Maxwell's equations, with a simple dipole antenna and spark gap oscillator. Thomson's experiments with cathode rays (1897): J. J. Thomson's cathode ray tube experiments (discovers the electron and its negative charge).

    en.wikipedia.org/wiki/History_of_radar

    In Hertz's 1887 experiment he found that these waves would transmit through different types of materials and also would reflect off metal surfaces in his lab as well as conductors and dielectrics. The nature of these waves being similar to visible light in their ability to be reflected, refracted, and polarized would be shown by Hertz and ...

    Heinrich Hertz. November – The Michelson–Morley experiment is performed, indicating that the speed of light is independent of motion. Heinrich Hertz discovers the photoelectric effect on the production and reception of electromagnetic waves in radio, an important step towards the understanding of the quantum nature of light.
