Detailed explanation-1: -In electromagnetic spectrum for wireless communication reserved range for radio waves and microwaves is known as ground propagation. Explanation: One sort of radio propagation, referred to as a surface wave, is ground wave propagation. These waves propagate over the earth’s surface in low and medium frequencies.
Detailed explanation-2: -Radio waves’ are electromagnetic waves used in different forms of wireless communication such as television, radios, and mobile phones. These devices convert the microwave radio waves mechanical vibrations in the speaker to make sound waves.
Detailed explanation-3: -The electromagnetic spectrum is comprised of all frequencies of electromagnetic radiation that propagate energy and travel through space in the form of waves. Longer wavelengths with lower frequencies make up the radio spectrum. Shorter wavelengths with higher frequencies make up the optical spectrum.
