ASSERTION : Dispersion is shown by the prism when white light passes through it. REASON : Different components of light are deviated by different angles when passed through a prism. Hence, it splits into its component colours​

Answer»

Since different colors of LIGHT travel at different speeds, the refractive index is different for each color. As a result, when WHITE light passes through the refracting surface of the prism, its COMPONENTS bend into different ANGLES, causing the single beam of light to SEPARATE.
