can't understand your question

Answer 2

Answer:

The emergence of different colours of light from a triangular prism at different angles leads an observer to see the component colours of visible light separated from each other. Thus, deviation is caused in a prism. when a ray of light enters a prism, it deviates, thus is because of change in the refractive index.
