Question

what happensnwhen a beam of sunlight is passed through a glass prism? what is spectrum?

Answer 1

When a beam of sunlight is passed through a glass Prism the white light of sunlight splits into seven colours I.e Red , Orange , green, blue ,indigo and voilet .

this splitting of white light into seven colours is called the dispersion of light

this dispersion of white light occurs because colours of white light travel at different apeed s through glass prism
so they get refracted at different angles



The band of seven colours formed on White screen ,when beam of white light is passed through prism is called spectrum

~~~~The formation of spectrum shows that white light is made of seven colours

*****Red colour is the upper part of spectrum and is deviated the least


hope helped.
