What type of electromagnetic radiation are useful to plants?

Mainly visible light.


What kind of EMR helps fight cancer?

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.


Which do you think is most useful type of radiation?

It depends on the context. In medical treatments, ionizing radiation like X-rays and gamma rays are commonly used. In communication and technology, non-ionizing radiation like radio waves and microwaves are more useful. Ultimately, the most useful type of radiation is the one that best suits the specific application or need.


Which type of radiation in the electronmagnetic spectrum is the least energetic?

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.


What form of electromagnetic radiation has the shortest wave length and highest energy?

Gamma rays have the shortest wavelength and highest energy among all forms of electromagnetic radiation. They are produced by the decay of atomic nuclei and are highly penetrating, making them useful in medical imaging and cancer treatment.


What does the earth's atmosphere do to most types of electromagnetic radiation?

The Earth's atmosphere absorbs and scatters most types of electromagnetic radiation, filtering out harmful ultraviolet (UV) radiation from the sun and allowing visible light and some infrared radiation to reach the surface. This natural filtering process helps protect life on Earth by regulating the amount of radiation that penetrates the atmosphere.


What do you think is the greatest advancement in the information and communications technology industry over the last 10 years?

BBG Communications Scholarship? Me too hahaha hahaha....me three guys !! Same! Anyone find a useful website or anything? (Not necessarily your answer)


What wave has the most penetrating radiation found in the electromagnetic spectrum?

X-rays have the most penetrating radiation in the electromagnetic spectrum. They can penetrate soft tissues, making them useful in medical imaging such as X-rays and CT scans. However, prolonged exposure to X-rays can be harmful to living organisms.


Does germanium emit far infrared radiation?

Yes, germanium does emit far infrared radiation. Infrared radiation is part of the electromagnetic spectrum, and germanium is known for its semiconducting properties that allow it to emit and detect infrared radiation. This property makes it useful in various applications such as night vision devices and infrared sensors.


What is gamma ray in physics?

Gamma rays are a form of electromagnetic radiation with high frequency and energy, typically emitted during radioactive decay or nuclear reactions. They have the shortest wavelength and highest energy in the electromagnetic spectrum, making them useful in various fields such as medicine and astrophysics.


Why is wind useful in technology?

Wind is useful in technology because it can create energy.


What is the movement of heat in the form of electromagnet waves called?

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.
