Document Summary
Light travels as a wave that can vary in two respects: Indication of perceived colour: variations in wavelength affect perception of color, high frequency: smaller wavelengths refer to light waves w/ a higher frequency, low frequency: larger wavelengths refer to light waves with a lower frequency. The visible spectrum is the tiny portion of wavelengths humans are sensitive to. Shortest wavelength we can see around 630 nanometers, which looks violet and longest wavelength we can see is around 750 nanometers, which looks red. Tuesday, february 6, 2018: visible spectrum only from a human perspective. There are other species which can see light outside our visible spectrum. Purity: affects the perception of richness + saturation of colours. This light described as desaturated: most of colors we see in everyday life not pure but mixture of wavelengths and less intense than pure colors. Light passes through the curved cornea, which begins focusing process.
