red
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.
The color that can be bent the least by a prism is red. This is because red light has the longest wavelength of all visible light colors, making it less susceptible to bending when passing through a medium like a prism.
Radiowaves have the longest wavelength of all electromagnetic waves (which also includes visible light, and for example x-rays).
White light is what we see when light of all (or most) of the frequencies in the visible spectrum are emitted together from the same source. It is the combination of every visible light wave.
Red light has the longest wavelength among all the colors in the visible spectrum.
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.
The visible light part of the electromagnetic spectrum is below the ultraviolet but above infrared. Purple light has the highest wave length and red has the lowest.
White light is what we see when light of all (or most) of the frequencies in the visible spectrum are emitted together from the same source. It is the combination of every visible light wave.
The visible light with the shortest wavelength is the last color you can see on the blue/violet end of the rainbow. It's not exactly the same for all eyes.
Visible light is a subset of the electromagnetic spectrum. Starting at the longest wavelengths (lowest frequencies), the electromagnetic spectum includes:Radio wavesMicrowavesInfra-redVisible lightUltravioletX-raysGamma raysRefer to the related link below for additional informaiton.
Of the colors in the visible spectrum, red has the lowest frequency and the longest wavelength. As you move on "up" the spectrum, wavelengths get shorter.Red has the longest spectrum of all visible light. But infrared is even longer and there are many more "colors" but you can't see them.
Ultraviolet light, visible light, X-rays, microwaves, radio waves, infrared waves, and gamma rays are all on the spectrum of light, are all electromagnetic waves (EM waves). Any EM wave can be considered light. EM waves are composed of photons, which has properties of both a particle and a wave. The difference between different waves on the EM wave/light spectrum is their frequency. For example, radio waves have a very low frequency, microwaves have a slightly higher frequency, then infrared, visible light, ultraviolet, X-rays, gamma rays, etc.
