Light Beam Path for a Prism

The light beam dispersion rainbow color effect of a prism. When white light shines on a prism surface it is broken down to different color components based on wavelength and refractive index variations.

Light Beam Path for a Prism

The refractive index for light at the interface between two media varies with the wavelength of the light.

  • Blue light: wavelength λ between 420 and 490 nm
  • Red light: wavelength between 650 to 750 nm

When white light shines on a prism surface it is broken down to different color components.
