Today Google’s search home page logo is decorated with a colourful wave animation to honour the birthday of Heinrich Rudolf Hertz. Heinrich Rudolf Hertz is a German physicist who has done extensive research on electromagnetic theory of light. He was born at Hamburg on February 22, 1857.
The unit of frequency of a radio wave is named after Hertz and his theory is the basis for the development of radio, television and radar.
Unlike the recent doodle that used complex Java Script for animated doodles, Hertz animation is a simple gif image animation.
