Answer 2

$\textbf{\underline{\underline{Dispersion\:Through\:Glass\:Prism :}}}$

$\star$ A Prism is a piece of transparent material bounded by two plane surfaces inclined at an angle. We generally Use Prism Of Triangular Faces.

$\implies$ It was in the year 1686 when Sir Issac Newton did his well-known experiment on passage of white light through a glass prism. He made a narrow pencil of light to fall on a glass prism. The emergent light was recieved on white screen. It was observed that there were Seven Colours appearing on screen; the colours that we see in rainbow. A prism,unlike a parallel faced rectangular glass block,was not only deviating, or bending, an incident ray towards its base but was also splitting white light into 7 colours. We call this phenomenon as Dispersion.
