Ibn Alhazen is considered the ÒFather of Optics.Ó  He wrote the ÒBook of OpticsÓ, which correctly explained and proved the modern theory of vision.  His experiments on optics greatly influenced later scientists. 
     His experiments included ones on lenses, mirrors, refraction, reflection, and the dispersion of light into its constituent colors.  He studied the electromagnetic aspects of light, and argued that rays of light are streams of energy particles traveling in straight lines.
