heinrich hertz
maxwell's predicted waves included waves at very low frequencies compared to infrared, which in theory might be created by oscillating charges in an ordinary electrical circuit of a certain type. attempting to prove maxwell's equations and detect such low frequency electromagnetic radiation, in 1886 the physicist heinrich hertz built an apparatus to generate and detect what are now called radio waves. hertz found the waves and was able to infer (by measuring their wavelength and multiplying it by their frequency) that they traveled at the speed of light. hertz also demonstrated that the new radiation could be both reflected and refracted by various dielectric media, in the same manner as light. for example, hertz was able to focus the waves using a lens made of tree resin. in a later experiment, hertz similarly produced and measured the properties of microwaves. these new types of waves paved the way for inventions such as the wireless telegraph and the radio.
