The longest wavelength for visible light is red. Anything longer than that (and with less frequency) would be infrared, or eventually radio waves.
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.
Radiowaves have the longest wavelength of electromagnetic 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 have the longest wavelengths in the electromagnetic spectrum
The electromagnetic spectrum includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. Of these, radio waves have the longest wavelength and lowest frequency, while gamma rays have the shortest wavelength and highest frequency.
The longest waves of light are red. In the visible light spectrum, red light has the longest wavelength, which is around 620-750 nanometers.
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)
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.
The light with the longest wavelength, which is still visible for us, is red light.
Radiowaves have the longest wavelength of all electromagnetic waves (which also includes visible light, and for example x-rays).
Radiowaves have the longest wavelength of electromagnetic waves.
Radio waves have the longest wavelengths.
Radio waves have the longest wavelengths.
