Quarter 9 is all about introductions about the topic Radiation and all of this information is found here.

Radiation

I did a research on understanding Radiation in forms of AM/FM and Hertz You can read it here:

▪ WHAT ARE HERTZ? Hertz is the amount of oscilation per second, it is the unit of frequency. The name comes from Heinrich Rudolf Hertz, he was the first one to provide proof of the existence of electromagnetic waves at around 1865. At around 1960 it was made official by the CGPM that frequency was now called Hertz. Before this frequency was expressed as ‘cycles per second’, such as ‘kilocycles’ & ‘megacycles’.
