When electromagnetic waves travel through a medium--anything other than a true vacuum--they slow down to less than the speed of light in a … WebOct 16, 2024 · 3 Answers. In 1856 with Rudolf Kohlrausch (1809–1858) he (Wilhelm Eduard Weber) demonstrated that the ratio of electrostatic to electromagnetic units produced a number that matched the value of the then known speed of light. This finding led to Maxwell's conjecture that light is an electromagnetic wave.
