WebThen, in 1999, researchers at Harvard University were able to slow a beam of light down to 38 miles an hour (61 kilometers per hour) by passing it through a state of matter known as a Bose-Einstein condensate. That's … WebThe sensation of color is produced by the physical stimulation of light detectors, called cones, in the human retina. The spectrum of colors produced by a prism is referred to as spectrally pure or monochromatic. They are related to the wavelength, as illustrated in Fig. 1.2.
