Biography
Philipp Eduard Anton von Lenard was a Hungarian–German experimental physicist who received the Nobel Prize in Physics in 1905 for his work on cathode rays. This work led to his experimental realization of the photoelectric effect, discovering that the energy (speed) of the electrons ejected from a cathode depends only on the frequency, and not the intensity of light.
