Document Summary

The adequate stimulus (type of physical energy to which a sensory receptor is especially tuned) for vision is light. We must first understand the physical characteristics of light; light is a form of electromagnetic energy. The electromagnetic radiation to which we are sensitive is a very small part of the electromagnetic spectrum. Light is made up of particles, called photons (particles that transmit light) The colour/hue we see depends on the wavelength (distance from crest of one wave to the crest of next) of frequency. The brightness depends on the intensity, which depends on amplitude (height of each wave) Cornea - clear layer that covers the front portion of the eye and contributes to our ability to focus our vision on an object. Pupil - opening (black circle) in the middle of the iris (colours part) of the eye; the pupil changes size to increase or decrease the amount of light entering.
