Document Summary
Light refers to radiation that occupies a relatively narrow band of the electromagnetic spectrum. It travels in waves that vary in terms of two different properties: length and amplitude. Wavelength - refers to the distance between peaks of a wave: differences in wavelength correspond to different colors on the electromagnetic spectrum. Long wavelengths - correspond with the reddish colors. Short wavelengths - correspond with the bluish colors. Amplitude (height) - the peaks of a wave gives different experiences. Sclera - is the white, outer surface of the eye. Cornea is the clear layer that covers the front portion of the eye and also contributes to the eye"s ability to focus. Light enters through the cornea and passes through an opening called the pupil. Iris a round muscle that adjusts the size of the pupil; it also gives the eyes their characteristic color. Lens - a clear structure that focuses light onto the back of the eye.
