Dispersion of Light (Prism)

White light splits into VIBGYOR through a prism because each colour bends by a different amount — red bends least, violet bends most. "Violet Is Bent the most."

🌏 In real life

After a monsoon shower, sunlight passing through raindrops splits into a rainbow — each drop acts like a tiny prism, dispersing white sunlight into its colours.

📝 Quick notes

  • Dispersion is the splitting of white light into its seven colours (VIBGYOR).
  • It happens because different colours have different wavelengths and refract (bend) by different amounts.
  • Red light bends the least; violet light bends the most.
  • A glass prism produces a band of colours called a spectrum.

🎯 Test yourself

Which colour bends the most and which the least when passing through a prism?

Violet bends the most; red bends the least.
