In following diagram shows a thin beam of white light from a source S striking on one face of a prism.
A slit is placed in between the prism and the screen to pass only the light of green colour. What will you then observe on the screen?
(i) Draw a diagram to show the splitting of white light by a prism into its constituent colour.
(ii) Draw another diagram to show how the colours of spectrum of white light can be combined
to give the effect of white light.
Light of different colours is deviated through different angles, by a prism. Explain the reason.
Give a reason, why the violet colour of white light deviated most and red colour of white light deviated least.
