Electromagnetic radiation is emitted from many different things. Some of the things that emit electromagnetic radiation are microwaves, x-rays and radios.
No, radiation travels in straight lines (except for charged particle radiation in electromagnetic fields, which follows arc shaped paths). However you can breath in matter that is emitting radiation.
The process described is radioactive decay.
A pulsar is an extraterrestrial source emitting regular waves of electromagnetic radiation which is believed to be a rapidly rotating neutron star.
No, steam is matter: water in its gas state.However being quite hot steam is emitting far more electromagnetic radiation (in the infrared band) than liquid water does.
Milli rems is a unit of X-ray radiation. Microwaves oven works by emitting electromagnetic waves using strong radiation, through a powerful transformer.
Electromagnetic radiation (EMR) is important when studying photosynthesis because without sunlight emitting EMR photosynthesis cannot occur.
electromagnetic radiation, a.k.a. light.
Street lamps are designed to emit visible light. Some of them do this by first emitting ultraviolet radiation that is converted to visible light by a coating on the inside of the light bulb.
Yes, laser stands for Light Amplification by Stimulated Emission of Radiation and is a mechanism for emitting electromagnetic radiation, typically Lightor Visible_light, via the process of Stimulated_emission
yes
In gamma rays atom becomes more stable by emitting excess energy in the form of gamma radiation. Gamma rays are part of the electromagnetic spectrum.
Convection and radiation (internally) and radiation (externally).
