Answer 1

Answer:

Radiation is energy that comes from a source and travels through space at the speed of light. This energy has an electric field and a magnetic field associated with it, and has wave-like properties. You could also call radiation “electromagnetic waves”.

Answer 2

Explanation:

In physics, radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium.[1][2] This includes:

electromagnetic radiation, such as radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma radiation (γ)

particle radiation, such as alpha radiation (α), beta radiation (β),proton radiation and neutron radiation (particles of non-zero rest energy)

acoustic radiation, such as ultrasound, sound, and seismic waves (dependent on a physical transmission medium)

gravitational radiation, radiation that takes the form of gravitational waves, or ripples in the curvature of spacetime.
