Question
  1. A ray of white light breaks up into its components while passing through a glass prism. Draw a ray diagram to show the path of rays?
  2. Mark the least deviated colour in your diagram?
  3. Why do different coloured rays deviate differently in a prism?

Answer


Different coloured rays deviate differently in a prism because different colours travel at different speeds through the glass prism.
