Light is the visible part of electromagnetic radiations. Visible light consists of radiations having a wavelength between 390-760 nm (or 3900-7600 mathringA). It can be resolved into light of different colours - violet (390-430 nm), blue or indigo (430- 470 nm), blue-green or blue (470-500 nm), green(500-580 nm), yellow (580 - 600 nm), orange (600-650 nm), orange-red (650-660 nm) and red (660-760 nm).
