Red is the only color in the rainbow spectrum that is spelled with only 3 letters. Red is the only color in the rainbow spectrum that is spelled with only 3 letters.
An optical prism can be used to disperse light from the sun's spectrum into all of its constituent colors. It is the same concept that gives rise to the phenomenon of rainbows.
the primary colors of the rainbow are red blue and yellow
Prisms create spectrum of colors by the cause of refraction.
The question probably refers to a light spectrum, and the most familiar apparition of that is a rainbow. If Nature isn't cooperating at the moment, one can make a mini-rainbow by holding a garden hose on the "spray" setting and standing with one's back to the Sun. Technically, the range of visible light is less than one octave on the whole spectrum of Electromagnetic radiation, which covers more than sixty octaves, so there's a lot of spectra we can't see at all. Fun Fact: No two people ever see the same rainbow, because it's not a "thing" but an effect. Each droplet of water acts as a tiny prism and contributes a different bit of light to each eye.
Has a different wavelength and energy. At the red end of the spectrum the wavelength is longer and frequency is lower, it will be less easily refracted than light towards the blue end of the spectrum, which is higher in frequency and has a shorter wavelength. The separation of the colours is called dispersion.
The colors of the spectrum were the colors of the rainbow.
A rainbow is a spectrum.
They represent the spectrum of colors in the atmosphere.
If there were colors, that part of the spectrum would not be invisible.
The visible spectrum
The White Light Spectrum.
The Visual Spectrum!
Visible Light Spectrum.
The Red spectrum of colors is always the outermost arc on a Rainbow while the Blue spectrum of colors make up the innermost arc
The colors are red, orange, yellow, green, blue, and purple. Basically the colors of the rainbow.
You see all the colors in a rainbow.
It can also be called a spectrum of colour!
