Wavelength: the distance between peaks of a wave: differences in wavelength correspond to different colors on the em spectrum, long wavelength = reddish colors, short wavelength = bluish colors. The different characteristics of light (wavelength, amplitude, and purity) are experienced as: hue: color of the spectrum. Sclera: the white, outer surface of the eye. Cornea: the (cid:272)lear la(cid:455)er that (cid:272)o(cid:448)ers the fro(cid:374)t portio(cid:374) of the e(cid:455)e a(cid:374)d also (cid:272)o(cid:374)tri(cid:271)utes to the e(cid:455)e"s ability to focus.
