WebThe meaning of DISPERSION is diaspora. How to use dispersion in a sentence. WebApr 6, 2024 · Light dispersion is caused only by refraction. After polychromatic light enters a big thick medium, refraction causes each colour to take a separate route. Snell's law dictates this. It states that sin (i)/sin (r) varies with light colour and medium. So the split light is the original incident light component.
