Document Summary

Overview of topics: physical properties of light, interaction of light with objects, anatomy of the eye. Light: a form of electromagnetic (em) radiation (along with gamma rays, uv light, radio, etc. , em radiation varies by, wavelength, intensity, polarity. Wavelength: abbreviated (lambda, measured in units of distance, such as angstroms or nanometers (nm, 1x10-9, visible light (to humans) ranges from, variations in wavelength give rise to colour. 400 nm to 700 nm experience, but relationship is complex. Wavelength: wavelength = 1/frequency frequency = 1/wavelength. Example: wavelength of . 001 seconds/cycle : with sound we talk mostly in terms of frequency. With light we talk mostly in terms of wavelength. 400-700 nm: why is vision limited to such a narrow range, one reason is that this is where most of the energy in sunlight is, some animals do see somewhat outside the human range, however.
