Radiation is defined as a process involving the transfer of heat from one place to another place without heating the intervening medium. The term radiation used here is another word for electromagnetic waves. These waves are formed due to the superposition of electric and magnetic fields perpendicular to each other and carry energy.
Types of radiation
Listed below are types of radiation
- Electromagnetic radiation: These include radiations such as microwaves, infrared, ultraviolet, radio waves, x-rays, and gamma radiation (γ), visible light.
- Particle radiation: These include alpha radiation (α), beta radiation (β), and neutron radiation.
- Acoustic radiation: Some of the popular ones are sound, ultrasound, and seismic waves.
- Gravitational radiation: This is a type of radiation that often takes the form of gravitational waves or ripples in the curvature of spacetime.
