Explanation:

Answer 2

Radio waves are the waves having frequency 30 Hz to 300 GHz

Explanation:

• Radio waves comes under the spectrum of electromagnetic waves and having a range of frequency from 30 Hz to 300 GHz ( giga hertz)
• Radio waves named as used in radio broadcasting and also for some other communication processes like in amplitude modulation, phase modulation, frequency modulation etc. Due to large band of wavelength these waves are used in communication
• Radio waves moves with the speed of light (3*10⁸ ms⁻¹) in air or vacuum and show all other properties as of electromagnetic waves
• Radio waves are artificially originate from the transmitter and received by the radio receiver and naturally occur in astronomical bodied and in lightning
