radiation
The part of the electromagnetic spectrum with the lowest frequency and longest wavelength is radio waves. They are used for communication, broadcasting, and radar.
radio waves (part of the electromagnetic spectrum)
The part that we call "Extremely Low Frequency Radio Waves".
Broadcasts such as infrared, microwaves, and radio waves are part of the invisible spectrum as they have wavelengths beyond the visible light spectrum and cannot be seen by the human eye. These forms of electromagnetic radiation are used in various technologies for communication, heating, and other purposes.
The radio wave part of the electromagnetic spectrum is typically used for communication because it can travel long distances and pass through obstacles like buildings or clouds. Radio waves have varying frequencies, which are used for different types of communication such as AM/FM radio, television, cell phones, and Wi-Fi.
Radio Frequency
We primarily use the visible light and radio waves parts of the electromagnetic spectrum. Visible light is essential for imaging and observation, while radio waves are widely used for communication and radar applications.

The electromagnetic spectrum
The electromagnetic spectrum consists of different wavelengths of electromagnetic radiation, ranging from radio waves to gamma rays. Each part of the spectrum has unique properties, such as frequency, energy, and interaction with matter. Different parts of the spectrum are used for various purposes, from communication (radio waves) to medical imaging (X-rays).
