Dispersion of Light is the phenomenon where light splits into its constituent colors (spectrum) when passing through a medium, such as a prism.
Identifying Monochromatic and Composite Light with a Prism:
- Monochromatic Light: It passes through the prism without splitting, remaining as a single color.
- Composite Light: It splits into a spectrum of colors when passed through the prism.
If the light remains a single color, it’s monochromatic; if it spreads out into a rainbow, it’s composite light.
