Luminescent. “Not Hot . Light. ”. Light . that does not need to be hot to glow. . Ultraviolet (UV) light falls in the range of the EM spectrum between visible light and X-rays. UV . light, which comes from the sun, is invisible to the human eye. .. It . makes black-light posters glow, and is responsible for summer tans — and sunburns. Can you think of a method to have the robot follow the line using turns? Describe how it would work.. 2. Pre-Activity Quiz. How does a light sensor work? Does the light sensor detect white or black as a higher amount of light reflectivity? Absorbance?. Dispersion of light. Visible light = full spectrum . wavelengths range from 400 nm to 700 nm. Different wavelengths have ever so slightly different indices of refraction when passing through materials such as glass, plastic, or water (and probably others). an LBTI Key project . Phil Hinz.

Bill Reach. Associate Director for Science. Stratospheric Observatory for Infrared Astronomy. Why Study the Smaller Bodies?. Tracer of gravitational potential. Sample of material from solar nebula and major bodies. The elementary particle that defines light is the photon.. There are 3 basic dimensions of light. Intensity (amplitude) which is related to the perception of brightness. Frequency (wavelength), perceived as colour.
