Question

Give examples of radiation.

Answer 1

Radiation

1. Radiation is defined as the energy which travels through space in the form of waves or particles.
2. Hence, radiation is also a form of transfer of energy that does not necessarily depend on the presence of a medium.
3. Radiation can be either ionizing or non-ionizing depending on the energy of the radiating particles or waves.
4. Ionizing radiations are generally high-energy radiations, while non-ionizing radiations are low-energy radiation.
5. There are mainly four types of radiation:

1. Electromagnetic radiation
2. Particle Radiation
3. Acoustic Radiation
4. Gravitational Radiation

Non-ionizing radiation example

1. Radio waves
2. Microwaves
3. Visible light
4. Infrared light
5. Light from the sun
6. Lasers

Ionizing radiation examples

1. X-rays
2. Alpha rays
3. Beta rays
4. Gamma rays
5. Ultraviolet light
6. Cosmic rays
