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.
Light at 489 nanometers is in the blue area of the spectrum. Use the link below for more information.
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.
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 colours are determined by the wavelengths of the light. How they are perceived depends on the brain interpreting the signals from the retina.
yellow
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].
ultraviolet light
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.
The entire electromagnetic spectrum travels at the same speed. The speed of light.
white light is not a single color..it is made up of 7 different colors which include red and blue and yes it is there in the electromagnetic spectrum between ultraviolet and infrared radiation
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
You cannot see ultraviolet rays, you can only see electromagnetic waves that are within the visible light spectrum; therefore it does not have a color. It is simply referred to as ultraviolet because its respective band on the EM spectrum lies above our visible violet frequencies.
Each chemical element has a different spectrum; and each color has a specific wavelength.
Blue and Green make the color Red in the Electromagnetic (EM) Spectrum.
Red, I believe.
