Why do you not see a spectrum of colours when light passes through a flat pane of glass?
Explain briefly, with the help of a neat labelled diagram, how white light gets dispersed by a prism. On which surface of a prism, there is both dispersion and deviation of light, and on which surface of the prism, there is only deviation of light ?
The diagram below shows the path taken by a narrow beam of yellow monochromatic light passing through an equiangular glass prism.
