That's the last color you can see on the redend
of the rainbow or other spectral display. It's not
exactly the same for all eyes.
Visible light is made of rays. There are rays with wavelengths that are shorter than visible light and other with longer wavelength.
It is electromagnetic radiation, which is the same in composition as visible light but has a much higher frequency/shorter wavelength, and will do damage to any biological material it passes through. Both travel at the same speed ('velocity of light') but gamma radiation can penetrate material opaque to visible light.
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.
X-rays have the highest frequency in the electromagnetic spectrum.
There are an infinite number of wavelengths above visible, below visible, and within visible. Since reality has infinite resolution, we can imagine varying the wavelength with infinite division. To call out bands of wavelength: Ultraviolet, X-rays, & Gamma rays.
Radiowaves have the longest wavelength of all electromagnetic waves (which also includes visible light, and for example x-rays).
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)

Yes, it's visible light rays which enable us to see; these rays are in the middle of the electromagnetic spectrum, between ultraviolet (which has a shorter wavelength) and infrared which is a longer wavelength. The visible light rays are divided into the 7 colours of the rainbow, with violet having the shortest wavelength & red the longest.

radiowaves, microwaves, infra-red, visible, ultraviolet, x-rays, gamma rays
Wavelength of violet is the shortest and that for red is the longest in the visible region. So for ultra violet the wavelength is to be less still and that for infra red it has to be larger than red So wavelength increases as we move through UV, visible and IR.
No--ultraviolet, x-rays, and gamma rays are progressively shorter.
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.

We know that ultraviolet light, X-rays and gamma rays have wavelengths shorter than visible light.
