Questions
The diagram below shows the path taken by a narrow beam of yellow monochromatic light passing through an equiangular glass prism. If the yellow light is replaced by a narrow beam of white light incident at the same angle, draw another diagram to show the passage of white light through the prism and label it to show the effect of prism on the white light.
The path taken by a narrow beam of yellow monochromatic light travelling through an equiangular glass prism is shown in the figure. If the yellow light is replaced by white light with the same angle of incidence, show the path of white light through the prism using a neat, labelled diagram.
