The existence of varying visible and invisible wavelengths was confirmed
     by Newton, when he used a glass prism to absorb white light, he found the

     prism reflected the white light as individual wavelengths. (Fig5.)

     Newton’s experiment with the prism explained Absorption and Reflection as

     seen by the human eye.

     The prism is made of glass without pigments. Thereby, it is completely

     transparent. When all the wavelengths in white light (Daylight) are absorbed

     they separate into individual wavelengths when reflected.
