Answer:
Option - a
Explanation:
The phenomenon explained in the question is termed dispersion. It is the splitting of white light into its constituent colors. Refraction is the phenomenon behind dispersion. Refraction occurs when light enters from one medium to another. More specifically speaking, Refraction occurs due to the difference in speed of light as it passes from one medium to another.
So we can say dispersion is caused due to refraction. Both the assertion and reason are true and the reason is the correct explanation of the assertion.
