Dispersion of White Light by a Glass Prism

  • Sunlight or White Light is made of 7 colors as in VIBGYOR(Violet, Indigo, Blue, Green, Yellow, Orange, Red). When white light is passed through a prism, we can see it split into the components that it is made of. This is called the Spectrum.
  • Violet bends the most and Red bends the least

  • Newton first discovered this and then he passed this spectrum of light through an another prism as shown and he observed that again white light emerged. This proves that white light is made of VIBGYOR colors
