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 electromagnetic radiation is the least energetic?
Perhaps you mean one of these, I can't tell:Alpha particle radiation: least penetrating ionizing radiation, 100% shielding provided by one sheet of paper.ELF radio: lowest energy radio waves (~0.01Hz), travels long distances and through water. U.S. Navy experimented with it for communicating with Submarines.Red light: Lowest frequency of visible light.Violet light: Shortest wavelength of visible light.Very High Energy Gamma radiation: Shortest wavelength of any known radiation.Anyway, least in what way?
What type of radiation has the least ability to penetrate matter?
The Least penetrating form of radiation is Alpha as it only travels 10cm in air and is stopped by paper. Alpha is also the most ionising, Beta is less ionising still and Gamma is the least ionising as photons carry no charge so they have less effect.
What types of electromagnetic radiation have the least energy?
Radio Waves have the longest wavelength of any EM radiation, so they usually have the least energy.
What is the weakest energy wave?
Among the many categories of radiation in the electromagnetic spectrum, the radiation with the lowest frequency(longest wavelength) carries the least energy. This might be the audio-frequency radiation from speaker-wires,the 60-Hz radiation from utility power lines or AC line-cords within the home, etc.
What type of radiation causes most ionisation?
The electromagnetic radiation most capable of ionizing is the radiation with the highest energy per quantum. That in turn implies the radiation with the highest frequency (shortest wavelength). The highest-energy end of the electromagnetic spectrum is the region we call "gamma rays". We can't generate these, and the gamma rays we observe all originate in radioactive nuclear processes.
What are the sections of the electromagnetic spectrum from least energetic to most energetic?
r u sus
What is the least energetic wave located at the end of the spectrum?
radio waves
What electromagnetic spectrum band has the least amount of energy?
The radio band is the least energetic section of the electromagnetic spectrum.

Energy is usually transferred in fluids by radiation?
No, the principle method of heat transfer in fluids is convection, as the most energetic molecules rise towards the surface and the least energetic sink. Radiation is most significant for objects which are very hot, even glowing.
What is the sequence of waves from most energetic to least energetic?
there is no waves HA WAVE CHECK

How do scientist estimate the temperature of the sun?
We don't need to estimate it, we can measure it (at least the surface temperature) using the cavity radiation equation and experimental observation of the solar spectrum.
Which color is more energetic red or yellow?
Red... Red is the most energetic color in ROY G BIV violet being the least energetic.
