Original Khojo Papers practice question — not from a past board paper.
Answer
Dispersion is the splitting of white light into its constituent colours when it passes through a prism. In order they are violet, indigo, blue, green, yellow, orange and red.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
Dispersion happens because the refractive index of the glass is different for each colour, so each is deviated by a different amount.
