Radiation is any process that transfers energy from one object to another by emission of "rays" of some type. There are many different kinds of "rays" that can do this, probably the most familiar is heat rays or IR that are emitted by hot objects into the cooler ambient environment around them heating it.
A few other types of "rays":
- radio and microwave, photons emitted by the transmitting antenna and absorbed by the receiving antenna
- alpha and beta particles, helium nuclei and electrons emitted by decaying atomic nuclei
- x-rays, photons emitted when extremely highly excited electrons in atoms return to more normal energy levels
- gamma rays, photons emitted by decaying atomic nuclei
- neutrons, emitted when atomic nuclei fission or fuse
- etc.
All "rays", whatever their form, are capable of traveling through a vacuum. Other means of transferring energy from one object to another require some physical medium made of matter of some kind.

What happens is the electricity goes through the wire and into the bulb to produce and beaming light into the room. It makes you feel much better with a bright and happy home to live in.

∙ 11y agoThis is the transfer of heat in waves, unlike conduction and convection which both transfer heat energy through particles, radiated heat can travel through a vaccum ie. an empty space with no particles within it.
I hope this helped answer your question.

Does radiation need atoms and molecules to work?
nope
Nuclear medicine techniques work through the detection of this kind of radiation injected into the body by adding a radioisotope to a certain drug?
Gamma rays are a type of radiation. Nuclear medicine techniques work through the detection of this kind of radiation injected into the body by adding a radioisotope to a certain drug.
How does oxybenzon work in sunblock?
In sunscreen, the oxybenzone specifically absorbs UV radiation. It then dissipates the UV radiation as heat, though this can theoretically cause minor damage to the body.
How do three types of heat transfer work together to heat the trosphere?
convection,radiation,and conduction?
Why do people exposed to radiation regularly need to wear radiation badges?
The radiation badges tell you how much radiation you have been exposed to so you know when you have been exposed to enough (before it becomes dangerous) and you can stop work in that area until you are able to be exposed to radiation again. They sometimes wear lead aprons to protect themselves from radiation. I think this is right but you had better check again somewhere else because it might not be right.
Why do workers work far from the source of radiation?
Ionizing radiation can cause cancer.
True or false cellular phones produce radiation?
True - they work by using microwave radiation.
Why do mobile phones need radiation to work?
because without radiation it wouldn't have access to web without it
Does radiation need atoms and molecules to work?
nope
How do radioactive implants work?
Interstitial radiation therapy places the sources of radiation directly into the tumor and surrounding tissue.
Is radiation always effective in shrinking a brain tumor?
Theres always a chance that radiation will not work... as there is with any method.
Do radios emit radiation?
Well, yes. They couldn't work if they didn't emit electromagnetic radiation in the form of radio waves.
Do radiation therapists work with other people?
Almost always.
Do ham radios emit radiation?
Well, yes. They couldn't work if they didn't emit electromagnetic radiation in the form of radio waves.
What is thermal radiation explaining it so i understand it but precisely for Year 9 assessment work?
Thermal radiation is a type of electromagnetic radiation caused by the movement of charged particles in any matter.
Who works with xrays radiation nuclear medicine and ultasound?
Radiologists work with these.
What form of heat transfer lets infrared cameras work?
Radiation
