Question
What is dispersion? Explain in detail.
Solution
- Splitting white light into its seven constituent colours (wavelength), on passing through a transparent medium is known as dispersion of light.
- Dispersion occurs because the light of different colours present in white light have different wavelength and they travel at different speeds in a medium.
- The refraction of a light ray in a medium depends on its speed.
