    Putting white light through a prism we generally get a continuous specrum of colors depending the source of the light and the limits of the transparency of the material of the prism. Sunlight certainly includes ultraviolet and infra red light but glass is not transparent to ultra-violet.

    When we look closer at this continuous spectrum of light we find gaps that tell us about the source of the light and everything that light has passed through. Black gaps usually indicate that the light has passed through something which absorbs light of that particular color.

    This is a detailed spectrum of sunlight.
