Question

How is dispersions/refraction of light caused?​

Answer 1

Explanation:

When light travels from one medium to another, the speed of its propagation changes, as a result, it 'bends' or is 'refracted'. ... Because of this, the dispersion of white light into its spectrum of colours takes place when refracted through a prism...

Answer 2

Answer:

Hey Buddy here's ur answer

The cause of dispersion is that different colours of white light having different wavelengths deviate through different angles on passing through a glass prism. That is why they split on coming out from the prism along different directions
