what electromagnetic waves have the lowest energy?
27828
Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation. In order from highest to lowest energy, the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves.
817996
The lowest frequency portion of the electromagnetic spectrum is designated as “radio,” generally considered to have wavelengths within 1 millimeter to 100 kilometers or frequencies within 300 GHz to 3 kHz.
290587
Waves with a short wavelength have the most energy. Red waves have a relatively long wavelength (in the 700 nm range), and violet waves are much shorter - roughly half that. Because violet waves have the shortest wavelength of the visible light spectrum, they carry the most energy.
1444595
The electromagnetic waves with the highest energy are gamma waves (usually called gamma rays). The most energetic gamma rays appear to originate from extremely energetic stellar objects called pulsars and blazars.

Microwaves has the 6th lowest frequency. Radio waves has the lowest frequency and has the highest wavelength. Radio waves are the lowest-frequency waves in the EM spectrum. Radio waves can be used to carry other signals to receivers that sub...
341577
Radio waves have the longest wavelengths of the electromagnetic spectrum, and the lowest energy (or frequency).
684284
Gamma rays have the shortest wavelengths of the electromagnetic spectrum, and the highest energies. Gamma rays have such short wavelengths, that astronomers usually discuss them in terms of energy. Gamma rays have energies greater than about 100 keV (keV stands for kilo-electron volt.

Radio Waves -- The waves in the electromagnetic spectrum that have the longest wavelengths and lowest frequency are called radio waves. Radio waves are used to transmit information from the antenna of a broadcasting station to the antenna of your radio or TV.

The lowest frequency portion of the electromagnetic spectrum is designated as “radio,” generally considered to have wavelengths within 1 millimeter to 100 kilometers or frequencies within 300 GHz to 3 kHz. There is a wide range of subcategories contained within radio including AM and FM radio.
217547
When it comes to visible light, the highest frequency color, which is violet, also has the most energy. The lowest frequency of visible light, which is red, has the least energy.
761362
Gamma Rays (Wavelength < 10-12 meters) Gamma rays have the shortest wavelengths (< 0.01 nanometers ) and the most energy of any region of the electromagnetic spectrum. Gamma rays are produces by the hottest objects in the universe, including neutron stars, pulsars, supernova explosions.
178780
Radio waves and microwaves lie at the longer end of the spectrum of electromagnetic energy (kilometers and meters to centimeters and milimeters), while x rays and gamma rays have very short wavelengths (billionths or trillionths of a meter).
524542
From lowest energy to highest energy (red to blue) there are radio waves, microwaves, infrared, visible light, ultraviolet, x-rays and gamma rays. Each of them have their uses and, at the high energy end, they also have their dangers.
227087
Electromagnetic radiation ranges from the lowest frequencies of radio waves to the highest frequencies of gamma rays. Nuclear radiation is any emission that is the result of activity in the nucleus of an atom.
127133
Radio waves have the longest wavelengths of the electromagnetic spectrum, and the lowest energy (or frequency). Radio waves pick up where microwaves leave off.
1238717
Examples of electromagnetic waves include radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma rays. Radio waves have the lowest energy and frequency and the longest wavelength. Gamma rays have the highest energy and frequency and the shortest wavelength.
1323581
Gamma-ray photons have the highest energy in the EMR spectrum and their waves have the shortest wavelength. Scientists measure the energy of photons in electron volts (eV). X-ray photons have energies in the range 100 eV to 100,000 eV (or 100 keV). Gamma-ray photons generally have energies greater than 100 keV.
