The highest ever detected on the earth's surface is the EM radiation emitted from
the radio transmitters on top of the Petronas Twin Towers in Kuala Lumpur and
from the TV transmitters on the Willis (Sears) Tower in Chicago.
(Air-to-ground communication, transponder, and radar signals emitted from
commercial aircraft in flight are judged in a different category.)

What type of em radiation has shortest wavelength and most energy?
Gamma radiation
Is ultraviolet radiation is visible or invisible?
It's detected by means of a camera that is sensitive to infra-red light. Visible light forms only a tiny portion of the electromagnetic spectrum.
Why is it true to say that all EM radiation is light even though we can see only a small slice of the spectrum as visible light?
Visible light is a very small part of the EM spectrum and it is intellectual laziness to refer to all EM radiation as light.
What is the only way that energy from the sun can travel to the earth?
By radiation, mostly infra red, visible, and ultra violet EM radiation
How is EM radiation different from alpha and beta radiation?
EM radiation is essentially high energy light, with wavelengths ranging from 10 nanometers low energy x rays to 10 picometers high energy gamma rays. Beta radiation refers to high speed electrons while an alpha ray is a high speed proton.
What is the highest frequency part of EM spectrum?
That's the gamma radiation.
What type of light waves carry the most energy?
Gamma radiation is an extremely high frequency EM wave and is probably the common lightwave with the highest energy. Since energy is proportional to frequency, the highest energy wave would be that with the highest frequency.
What does electromagnetic have to do with EM radiation?
EM is short for electromagnetic.
What type of wave is EM radiation?
EM radiation is short for electromagnetic radiation. It is a wave in the electric and magnetic fields.EM radiation is short for electromagnetic radiation.

How can you recognize EM radiation?
EM radiation can be detected by a variety of devices according to its frequency and its amplitude. For example, a radio receiver (Marconi effect) can be used to detect EM radiation in the radio range, your eyes or a photometer (photoelectric effect) for EM rads in the visible, IR and UV range, thermoluminescent detectors can be used for ionizing EMs, etc. One simple way to differentiate between EM radiation and particulate radiation is to place a plastic or thin metal shield between the detector and the source. Particulate radiation, such as alpha, beta, positron, typically will not penetrate plastic shielding, and your count rate or exposure levels will decrease. Whereas EMR is penetrable, and will traverse the plastic, needing something more substantial, such as lead, before showing signs of significant reduction in exposure.
At what speed does all EM radiation travel at?
In a vacuum, 3x10^8 ms^-1. Basically the speed of light, it is EM radiation afterall.
What type of em radiation do conventional ovens use?
infrared radiation ;)<3
What type of em radiation has shortest wavelength and most energy?
Gamma radiation
What is the scientific term for light?
"electro-magnetic radiation" "electro magnetic radiation" em radiation
What distance does electromagnetic radiation travel in 10.7?
In 10.7 femtoseconds, em radiation will travel 3.208 E -6 meters. EM radiation travels at the speed of light, or 299, 792, 458 m/s.
From Where does the energy carried by an EM wave come?
The electromagnetic (EM) spectrum is a name for different types of radiation. Most radiation comes from the sun. Want more info?
What EM radiation that can be seen with the naked eye?
Visible light
