Splitting of White Light into Band of Colours, , The band of the coloured components of light, beam is called Spectrum i.e. VIBGYOR, , The splitting of light into its component colours is, called Dispersion., , The different component colour of light bends at, different angle with respect to incident angle, the, red light bends the least while the violet bends, most., , ISSAC NEWTON-— He was the first, who obtained, spectrum of sunlight by using glass prism., , He tried to split the spectrum of white light more, by using another similar prism, but he could not, get any more colours., , He repeated the experiment using second prism in, an inverted position with respect to the first prism., Allowed all the colours of spectrum to pass, through second prism. He found white light, emerges on the other side of second prism., , \ So, \, R “aN, “\iott R ’ ; wr, \ gin® . . yo, ye / \V, \, , st L \, sol \
