Question

briefly explain the couse of dispersion​

Answer 1

Explanation:

Dispersion occurs due to the different degrees of refraction experienced by different colours of light. ... This difference in the extent of bending of different colours of light of light results in the dispersion of white light into its constituent colours as they emerge from a prism.

Answer 2

The splitting up of white light into its constituent colours on passing through a refracting medium like a glass prism is called dispersion of light. The dispersion of white light occurs because different colours of light bend through different angles with respect to the incident ray, as they pass through a prism.
