What three characteristics distinguish all radio waves?

The characteristics that distinguish all radio waves are signal speed, wavelength, and frequency.

Signal speed refers to the speed of radio waves, which travel at the speed of light in a vacuum (approximately 299,792 kilometers per second). This fundamental property distinguishes radio waves from other types of waves, such as sound waves, which travel much slower.

Wavelength is the distance between successive peaks (or troughs) of a wave, which varies for different types of radio waves. The wavelength is inversely related to frequency; as the wavelength increases, the frequency decreases, and vice versa.

Frequency is the number of cycles of a wave that occur in one second, measured in Hertz (Hz). It is a critical property of radio waves because different frequencies are used for various communication purposes. Different parts of the electromagnetic spectrum, such as AM and FM radio, television, and other forms of wireless communication, operate at specific frequencies.

Together, these characteristics—signal speed, wavelength, and frequency—define the behavior and applications of radio waves in various technologies. Understanding these properties is essential for effectively operating radar systems and interpreting the signals they produce.
