Why should white light give seven colours?

Best Answers

White light is NOT made up of seven colours. The light that we can see ranges in wavelength from about 3500 to 7000 Angstroms; in principle, every different wavelength is a different colour and there are an infinite number of wavelengths in this range. read more

Colour is NOT a property of light, but a perception; our eyes have receptors that respond differently to different wavelengths of light. When we look at the spectrum of white light, we see six or seven colours (not all of us can see seven; most people can only see six). read more
