Electromagnetic energy radiated from an antenna is known as what type of waves?

Electromagnetic energy radiated from an antenna primarily manifests as radio waves. This is due to the specific frequency range that is produced by antennas designed for communication purposes. Radio waves are a part of the electromagnetic spectrum, which also includes sound waves, light waves, and infrared waves, but they are distinctly characterized by their ability to propagate through space and carry information over long distances.

Antennas operate efficiently within the radio frequency (RF) range, which is typically from about 3 kHz to 300 GHz. This frequency range is utilized for various communication technologies, including AM and FM radio, television broadcasts, and wireless communication systems like smartphones and Wi-Fi. The functionality of antennas is thus inherently tied to the propagation of radio waves, making this designation the most accurate.

In contrast, sound waves are mechanical vibrations that require a medium, such as air or water, and cannot propagate in a vacuum. Light waves, while part of the electromagnetic spectrum along with radio waves, represent a higher frequency range and are not the primary mode of transmission utilized by antennas for radio communications. Infrared waves are also part of the electromagnetic spectrum but occur at shorter wavelengths than radio waves and are used in different applications, such as thermal imaging and remote controls.
