What is radiation in physics?
In physics, radiation is the emission or transmission of energy in the form of waves or particles through space or a material medium. [1] [2] This includes:
Apr 11, 2024 · Radiation, flow of atomic and subatomic particles and of waves, such as those that characterize heat rays, light rays, and X rays. All matter is constantly bombarded with radiation of both types from cosmic and terrestrial sources. This article delineates the properties and behaviour of radiation.
Jan 25, 2023 · Radiation is energy that moves from one place to another in a form that can be described as waves or particles. We are exposed to radiation in our everyday life. Some of the most familiar sources of radiation include the sun, microwave ovens in our kitchens and the radios we listen to in our cars.
Electromagnetic radiation can be defined as a form of energy that is generated when electrically charged particles move through matter or a vacuum. Alternatively, it can also be produced by oscillating magnetic and electric disturbances. Let’s delve deeper into the key aspects of electromagnetic radiation:
- Electromagnetic radiation is a form of energy that is produced by the movement of electrically charged particles or oscillating electric and magnet...
- Electromagnetic radiation has several properties, including the ability to travel through empty space, constant speed of light, different wavelengt...
- The types of electromagnetic radiation include gamma rays, X-rays, ultraviolet (UV) rays, visible light, infrared (IR) rays, microwaves, and radio...
- Electromagnetic radiation is characterised by properties such as wavelength, frequency, amplitude, and energy. Different types of electromagnetic r...
- The electromagnetic spectrum refers to the entire range of electromagnetic radiation ranging from high-energy gamma rays to low-energy radio waves,...
Radiation includes particles and electromagnetic waves that are emitted by some materials and carry energy. The kind of radiation discussed below is called ionising radiation because it can produce charged particles (or ions) in matter. X-rays, gamma-rays, alpha particles, beta particles and neutrons are all examples of ionising radiation.
Radiation is energy that travels in the form of waves or particles and is part of our everyday environment. People are exposed to radiation from cosmic rays, as well as to radioactive materials found in the soil, water, food, air and also inside the body. Human-made radiation sources are widely used in medicine, industry, and research.
Mar 20, 2020 · Radiation is energy given off by matter in the form of rays or high-speed particles. All matter is composed of atoms. Atoms are made up of various parts; the nucleus contains minute particles called protons and neutrons, and the atom's outer shell contains other particles called electrons.
