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 wavelengths in the electromagnetic spectrum
Radiowaves have the longest wavelength of electromagnetic waves.
Between Yellow, Green and Violet, the Yellow color has the longest light wave. The order of the 7 rainow colors, sorted by their light waves from the longest to the shortest, is as follows: Red, Orange, Yellow, Green, Blue, Indigo and Violet.
Radio Waves
Radio waves have the lowest frequency and longest wavelength there arent any sub-catagories it just goes (lowest to highest in frequency) Radio wave, microwave, infrared, Visible light, ultra violet light, x-ray, then gamma ray with the shortest wavelength and highest frequecy
== ==
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.
Infrared light, microwaves and radio waves have wavelengths longer than visible light. Radio waves have the longest wavelength.
The light with the longest wavelength, which is still visible for us, is red light.
The electromagnetic waves with the longest wavelength are called "radio waves". There is no limit to how long the wavelengths can be.
Radiowaves have the longest wavelength of all electromagnetic waves (which also includes visible light, and for example x-rays).
Radio waves have the longest wavelengths.
Radio waves have the longest wavelengths.
Radio waves have the longest wavelengths.
"radio waves" have longest wavelength..
the waves with the longest wavelengths in the electromatic speectrum are radio waves.
