There are several other examples of electromagnetic radiation beyond the commonly known radio, infrared, visible, and ultraviolet regions. Here are a few additional examples:
X-rays: X-rays have higher energy and shorter wavelengths than ultraviolet light. They are commonly used in medical imaging, such as X-ray radiography and computed tomography (CT) scans, as well as in industrial applications and scientific research.
Gamma rays: Gamma rays have the highest energy and shortest wavelengths in the electromagnetic spectrum. They are produced by nuclear reactions, radioactive decay, and high-energy particle interactions. Gamma rays are used in medical imaging and cancer treatments, as well as in astrophysics to study high-energy phenomena.
Microwaves: Microwaves have longer wavelengths than visible light and are commonly used in microwave ovens for cooking. They are also used in communication systems, such as satellite communication and radar technology.
Terahertz waves: Terahertz waves, also known as T-rays, have wavelengths between microwaves and infrared light. They have various applications in imaging, security screening, and spectroscopy, including the detection of hidden weapons, explosives, and drugs.
Cosmic rays: Cosmic rays are high-energy particles, primarily consisting of protons and atomic nuclei, that originate from sources in outer space. They have extremely high energies and can be harmful to living organisms. Cosmic rays are studied in astrophysics and particle physics to understand the origins and properties of these energetic particles.
Radio waves: Although you mentioned radio waves in your question, it's worth noting that the electromagnetic spectrum extends beyond what is typically referred to as "radio waves." This region includes very low frequency (VLF), ultra-low frequency (ULF), extremely low frequency (ELF), and super low frequency (SLF) waves. These waves are used for long-range communication, submarine communication, and scientific research.
It's important to note that these examples represent different regions of the electromagnetic spectrum, which is a continuous range of electromagnetic waves characterized by their wavelengths and frequencies.
