he didn't
No. The radio was invented by Guglielmo Marconi.
Rudolf Hertz did not invent anything. He was a physicist who discovered electromagnetic waves and the photoelectric effect. Hertz's work laid the foundation for the development of radio technology.
1895, soon after James Clerk Maxwell, Sir Oliver Lodge, and Heinrich Hertz had done all the hard work.
The unit for measuring radio waves, the hertz (Hz), is named after German physicist Heinrich Hertz, who made significant contributions to the study of electromagnetism and radio waves in the late 19th century.

Radio
Hertz invented the electromagnetic wave to test James Clerk Maxwell's theory that light is a form of electricity. Hertz created electric waves and showed that they operated like light.
Marconi wanted to prove to his dad that he could send radio wave from England to newfound land pay waves.Guglielmo Marconit thought that it was important to invent the radio because it was an important attribute to the American culture and our history.We should be careful here. Marconi did not invent "the radio" in the sense that we use the word today: He invented something called the radiotelegraph---a practical application of a phenomenon discovered by Heinrich Hertz. Marconi did it because he thought he could make a lot of money. This turned out to be a good idea because he did, in fact, make quite a lot of money off it.
