Mobile phones use electromagnetic waves with frequencies in the microwave range.
All radio (and TV and GPS and cell-phones [all of which are really radios]) work by transmitting and/or receiving electromagnetic waves.
wow, I was tryig to ask the same question but it wasn't even answered I'm mad because I need it for H.W. and nothing else has the answer XO
Radio waves.

The users would likely know if an upgrade would be necessary or even useful.
Any time something is of measurable benefit with few or no adverse effects it can be called "useful". Technology has been useful in education for quite a long time now however. So called "super computers" were being used in collegiate education in the late 1960s, giving way to the evolution of spacecraft, computers, home electronics and literally hundreds of the biggest and most profitable companies in existence today. Technology is the future, and keeping children educated on the subject is their only hope for financial and social success, generally speaking. A shorter answer to the question is this: You can say technology is useful in education NOW.
Mainly visible light.
The type of electromagnetic radiation that is used to fight cancer is gamma radiation. Gamma radiation is a type of ionizing radiation, which breaks the chemical bonds in cells, which makes it useful in treating cancer.
It absorbs almost everything except the visible spectrum.
infrared radiation

The electromagnetic spectrum is a continuum. The least energetic type of radiation may be found in what is known as "extremely low frequency" radiation (ELF). This is radiation with a frequency in the range 3-30 Hertz. ELF radiation can penetrate seawater and so is particularly useful for communicating with submarines.
BBG Communications Scholarship? Me too hahaha hahaha....me three guys !! Same! Anyone find a useful website or anything? (Not necessarily your answer)
Wind is useful in technology because it can create energy.
The question is not very precise, so there could be a couple of answers you are looking for. If you mean what is the name of the process by which heat is removed from an object by emitting electromagnetic radiation then the answer is thermal radiation. Wikipedia has a fairly useful article of that title.
Certainly.
The radiation that are absorbed are not all useful. Only the harmful ones are.
yes, because how will they make computers? and how will they purify the water from injuries. that is why science and technology are useful
