Information Booster:
  • When a beam of pure white light passes through a prism, the light is dispersed into its constituent colors, creating a spectrum.
  • This occurs because different wavelengths (colors) of light bend at different angles as they pass through the prism, resulting in the separation of white light into various colors like red, orange, yellow, green, blue, indigo, and violet.
  • This process is called dispersion.
  • It happens because of the variation in the refractive index of the prism for different wavelengths of light.
