Which colour of light shows maximum deviation when passed through a prism? (1) Red (2) Green (3) Violet (4) Yellow
by

1 Answer

Answer :

(3) Violet Explanation: When passed through a prism violet colour of light shows maximum deviation. As white light passes through a prism, the voilet component, having the minimum wave length observes the maximum refractive index for the prism and, thus, gets deviated to the maximum extent.
