Question

Why does the light ray split when passed through a prism into its constituent colors?

  1. Light of different wavelength bend by different amounts 
  2. Lights of the same wavelength bend by  amounts
  3. Light of different frequencies bend by different amounts
  4. Lights of same frequencies bend by different amounts

hintHint:

The separation of visible light into its different colors is known as dispersion.

The correct answer is: Light of different wavelength bend by different amounts


    The white light is separated into its component colors - red, orange, yellow, green, blue, indigo and violet.
    When light rays enter the glass prism the angle at which it bends makes the light split into its seven components because the speed of each component of light is different and due to the bending every component shows its different ability to pass through it.
    Light of different wavelength bend by different amounts
