Q.What are radio waves? Give its two uses.

[!TLDR] Radio waves are the longest-wavelength EM waves, produced by accelerating charges in a circuit; they are used for wireless communication and for radio/TV broadcasting. [!ANSWER] EM waves of very long wavelength, produced b …

Section 13.3.1 defines radio waves as EM waves produced by the accelerated motion of charges in a conducting wire, with very long wavelengths ranging from a few centimetres to a few hundred kilometres, and frequency set by the inductance and capacitance of the producing circuit. Two representative uses from the same section: radio waves are used for wireless communication generally, and specifically for radio broadcasting and the transmission of TV signals (a third valid use …
