The electromagnetic spectrum is the range of all possible wavelengths or frequencies of electromagnetic radiation. It encompasses various types of electromagnetic waves, each with different properties and interactions with matter. The electromagnetic spectrum includes the following regions, listed in order of increasing frequency or decreasing wavelength: 1. Radio Waves: Radio waves have the longest wavelengths and lowest frequencies in the electromagnetic spectrum. They are commonly used for communication, including radio broadcasting, television signals, and wireless networks. 2. Microwaves: Microwaves have shorter wavelengths and higher frequencies than radio waves. They are used in microwave ovens, radar systems, and satellite communication. 3. Infrared Radiation: Infrared radiation has wavelengths longer than visible light but shorter than microwaves. It is emitted by warm objects and is commonly used in applications such as thermal imaging, remote controls, and infrared heating. ...
