Document Summary
Movement of photons through space produces oscillating electric + magnetic field that together move in the same direction as the photon. Mutually linked to each other + vary in intensity over time. Cause major source of electromagnetic radiation to the earth is the. Emission spectrum to sun restricted to narrow band of radiation spanning from 100-4000 nm (i. e. uv, vs, ir) Reaches surface of earth + transmission properties in atmosphere are: transmission spectrum of atmosphere has similar profile to. Sun"s emission spectrum + overlaps significantly: vs is comfortable in this region life evolved to take advantage of light as sensory stimulus = much of suns emission. Light transmitted along straight lines + at awesome speed. Vision = instantaneous sense allows us to perceive events with little. Rapid transmission of flight in eyes allows visual system to assume role as most distant sense. Speed of light in a vacuum is 299,792 km/s aka 186,282 miles/s.
