Wihlem Hallwachs in 1888 helped to clarify an experiment performed by this man the previous year, which eventually led to the discovery and theory behind the photoelectric effect.In his most famous experiment, using a Rumikoff-spark induction coil to generate electromagnetic radiation and constructed a "receiver" made of a copper wire bent into the shape of a circle and small brass sphere, he was able to detect and measure transverse free space electromagnetic waves, examples of which include radio waves. For 10 points, name this German Engineer and physicist who lends his name to the SI unit for frequency.
