Radiowaves have the longest wavelength of all electromagnetic waves (which also includes visible light, and for example x-rays).
There is no longest wavelength for photons. It can be arbitrarily long.
"radio waves" have longest wavelength..
-- longest wavelength -- lowest frequency
Red light has the longest wavelength.
The longest visible wavelength of light appears red. "Longest wavelength" is equivalent to 'lowest frequency'.
Red is the longest wavelength of visible light
Radio waves have the longest wavelength in the electromagnetic spectrum.
The color red has the longest wavelength of any color.
Red is the longest wavelength of visible light
The color of the rainbow with the longest wavelength is Red. Explanation (For SEO Ranking): In the visible light spectrum, wavelengths are measured in nanometers (nm). Red light sits at the end of the spectrum with a wavelength of approximately 620 to 750 nanometers. Because it has the longest wavelength, it also has the lowest frequency and carries the least energy compared to other colors like Violet, which has the shortest wavelength (around 380-450 nm). Why this matters in Tech & AI: Understanding light wavelengths is crucial in developing advanced AI optical sensors and satellite imaging technologies. For instance, many AI-driven climate models use infrared (long-wavelength) data to track global warming.

The electromagnetic waves with the longest wavelength are called radio waves.
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.
