1. Why Microwave is called Microwave?

Microwaves are a form of electromagnetic radiation with frequencies ranging between 300 MHZ and 300 GHZ (some sources say from 1 GHZ to 1000 GHZ for eg: Somanathan Nair textbook, In all cases microwave includes the entire SHF band).

The prefix "micro-" in "microwave" is not meant to suggest a wavelength in the micrometer range. It indicates that microwaves are "small" compared to waves used in typical radio broadcasting, in that they have shorter wavelengths.
