The colours are determined by the wavelengths of the light. How they are perceived depends on the brain interpreting the signals from the retina.
Frequency.
Yes, visible light (the color spectrum) is a tiny range of the full range of electromagnetic waves. In the related Wikipedia link, there is a picture that shows the colors 'crammed in' to a small range of the spectrum.
Red light.
Photons with higher energy correspond to electromagnetic radiation with higher frequency/shorter wavelength. In the visible band, the color with the highest frequency is the last one you can see on the VIOLET end of the spectrum.
The color spectrum is part of the electromagnetic spectrum. The color spectrum, often referred to as 'visible light' is only part of it. It is called visible light because it is the only spectrum that we can see with our eyes (we can't see x-rays, radiowaves, etc). The colors within it come in the order of ROYGBIV : Red, Orange, Yellow, Green, Blue, Indigo, Violet.
The color white reflects all wavelengths of the visible spectrum. That is why it is the brightest color.
The "color" is really a wavelength. The electromagnetic spectrum determines this, every different wavelength has a corresponding color. Red being the longest, and violet being the shortest. This electromagnetic spectrum also determines whether it is visible, ultraviolet, infrared, and so on.
The so called visible spectrum. (from red [low frequency] to violet [high frequency].
Yes, visible light (the color spectrum) is a tiny range of the full range of electromagnetic waves. In the related Wikipedia link, there is a picture that shows the colors 'crammed in' to a small range of the spectrum.
Red light.
Red, I believe.
Its not. You can't see ultraviolet. (it lies just above the visible spectrum.)
The color spectrum is made from all the wavelengths of visible light, with red at the lowest frequency and violet at the highest frequency that can be seen. Visible light is part of the electromagnetic spectrum that also includes radio and microwaves up to X-rays and gamma rays.
Ok, the electromagnetic spectrum is RadioWaves-Microwaves-Infrared-(red orange yellow green blue violet)-UltraViolet-XRay-Gamma These are part of the visible color spectrum So violet would be the answer.

"Color" is a way of describing how an object interacts with electromagnetic radiation in the visible region of the spectrum. This has no impact whatsoever on how it interacts with electromagnetic radiation in the microwave region of the spectrum. So, no, they don't.
Answer is simply yes , human eyes is only sensitive to the visible light at the electromagnetic spectrum , however there is a different in wavelength and the frequency depending on the color of the visible light
