The longest wavelength photon I could find out about was in a maser (microwave version of a laser) which uses emission between two hyperfine levels of atomic hydrogen. This had a frequency of 1.4 GHz and a wavelength of 21cm.
That's the last color you can see on the redendof the rainbow or other spectral display. It's notexactly the same for all eyes.
No, ultraviolet radiation has shorter wavelengths compared to visible light and infrared radiation. The electromagnetic spectrum orders radiation from longest to shortest wavelength as radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.
Red is the longest wavelength of visible light
The longest wavelength / lowest frequency visible light is the red end of the spectrum. The shortest wavelength / highest frequency visible light is the violet end of the spectrum.
Red light has the longest wavelength within the visible spectrum.
Radiowaves have the longest wavelength of all electromagnetic waves (which also includes visible light, and for example x-rays).
The longest wavelength is radio waves, followed by microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays, which have the shortest wavelength.
Of the items on that list, radio has the longest wavelength and x-rays have the shortest.
Radio waves have the longest wavelength compared to other types of electromagnetic waves such as microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.
That's the last color you can see on the redendof the rainbow or other spectral display. It's notexactly the same for all eyes.
for wavelength, the longer of the two is visible light, but the longest type of rays are radio waves (some of them have a wavelength as long as a football field)
No, ultraviolet radiation has shorter wavelengths compared to visible light and infrared radiation. The electromagnetic spectrum orders radiation from longest to shortest wavelength as radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.
The correct order of the electromagnetic spectrum from shortest wavelength to longest is gamma rays, X-rays, ultraviolet light, visible light, infrared radiation, microwaves, and radio waves.
The order of the energy spectrum from shortest to longest wavelength is gamma rays, X-rays, ultraviolet light, visible light, infrared light, microwaves, and radio waves.
Radio waves, microwaves, infrared, visible light, ultraviolet light, X-rays, gamma rays.
The longest visible wavelength of light appears red. "Longest wavelength" is equivalent to 'lowest frequency'.
X-rays have the shortest wavelength of those listed.
