  1. The visible spectrum (or sometimes called the optical spectrum) is the part of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light. A typical human eye will react to wavelengths in air from about 380 to 750 nm.

    What is visual spectrum?
    The visual spectrum, the wavelengths of light that the human eye can see, include long wavelength light (red) all the way through short wavelength light (blue). The visual spectrum includes all colors of the rainbow: red, orange, yellow, green, blue, indigo, violet. Red and orange have longer wavelengths and blue/indigo/violet have shorter ...

    What is Invisible Spectrum?
    invisible spectrum. The portion of the spectrum either below the red (infrared) or above the violet (ultraviolet), which is invisible to the eye, the waves being too long or too short to affect the retina. Hereof, what is the invisible spectrum of light? The human eye can only see visible light, but light comes in many other "colors"—radio ...

      Isn't the exact range of the visible spectrum disputed?--Luke Elms 20:33, 17 May 2008 (UTC) 1. Not that I know of. It is widely accepted that there is no "exact range", since the sensivities curves fall gradually to zero at both ends. Dicklyon (talk) 21:33, 17 May 2008 (UTC)

        The electromagnetic spectrum is the range of frequencies (the spectrum) of electromagnetic radiation and their respective wavelengths and photon energies.
        The electromagnetic spectrum covers electromagnetic waves with frequencies ranging from below one hertz to above 10 hertz, corresponding to wavelengths from thousands of kilometers down to a fraction of the size of an atomic nucleus. This frequency range is divided into separat…
