Discovery of radio waves
- Hertz's contribution to the spectrum was his discovery of radio waves. Hertz performed more experiments and was soon able to fully verify Maxwell's theory. He demonstrated that the energy radiating from his electrical oscillators could be reflected, refracted, and could produce interference patterns and standing waves similar to light.

Oct 12, 2012 · Heinrich Hertz was a brilliant German physicist and experimentalist who demonstrated that the electromagnetic waves predicted by James Clerk Maxwell actually exist. Hertz is also the man whose peers honored by attaching his name to the unit of frequency; a cycle per second is one hertz.
Jan 1, 2019 · In the late 1800s, a number of physicists attempted to detect and generate electromagnetic waves in order to prove James Clerk Maxwell's theory of electromagnetism, which was published in 1865. The first to actually accomplish this feat was Heinrich Hertz, who constructed an oscillator formed from brass knobs.
Dec 6, 2015 · The renowned scientist Heinrich Hertz was the first physicist to prove the existence of electromagnetic waves which was hypothesized in James Maxwell 's theory of electromagnetism.

In Module 6: Electromagnetism, we learnt about Faraday’s Law of Induction where an object experiencing change in magnetic flux experiences an induced emf. Faraday proposed that changing magnetic fields produced electric fields.
Maxwell’s contribution to electromagnetism allowed for more accurate methods to be used to calculate the speed of light. In 1907, Rosa and Dorsey indirectly determined the speed of light through using the electric and magnetic permeability of air. This positive finding verified the existence of electromagnetic waves and confirmed that light in fact...
The German physicist Heinrich Hertz was the first to generate and detect certain types of electromagnetic waves in the laboratory. He performed a series of experiments that not only confirmed the existence of electromagnetic waves, but also verified that they travel at the speed of light. Figure 2: Hertz's experimental set-up.
