Wavelength: Radio waves have the longest wavelengths of any type of EM radiation, ranging from a few millimeters to several kilometers. This means that they have a lower frequency than other forms of EM radiation, and they can travel through objects that other forms of EM radiation cannot.
Frequency: Radio waves have frequencies that range from 3 kilohertz (kHz) to 300 gigahertz (GHz). This range is much lower than the frequencies of other forms of EM radiation, such as visible light, which has frequencies in the terahertz (THz) range.
Energy: Radio waves have very low energy compared to other forms of EM radiation. This means that they do not have enough energy to cause damage to living tissue or to interfere with electronic devices.
Uses: Radio waves are used for a wide variety of purposes, including communication, broadcasting, and navigation. They are also used in remote controls, garage door openers, and other electronic devices.
In summary, radio waves are a type of EM radiation that have long wavelengths, low frequencies, and low energy. They are used for a variety of purposes, including communication, broadcasting, and navigation.
