Which color deviates highest when passing through a Prism

Answer & Solution
Correct Answer: Option C
The wavelength and frequency of these deviated colours is different, they deviate differently at different angles due to the velocity difference of the prism. The colour red therefore deviates the least since it has maximum wavelength and colour violet deviates the most since it has the least wavelength.
