Gustav (ˈɡʊstaf). 1887–1975, German atomic physicist. He provided evidence for the quantum theory by his research with Franck on the effects produced by bombarding atoms with electrons: they shared the Nobel prize for physics (1925)
Heinrich Rudolph (ˈhainrɪç ˈruːdɔlf). 1857–94, German physicist. He was the first to produce electromagnetic waves artificially
The SI derived unit used to measure the frequency of vibrations and waves, such as sound waves and electromagnetic waves. One hertz is equal to one cycle per second. The hertz is named after German physicist Heinrich Hertz (1857-1894).
