Document Summary
Results of selective scattering of smaller particles than the wavelength of incident light and resonances at frequencies higher than scattered light. The tinier the particles, the higher the frequency of light it will emit. Due to selective scattering: small particles = smallest wavelength scattered ight, highest frequency. In the blue-violet end of the visible spectrum. Blue scattered light predominates in our vision. If there is a mix of blue and violet, you"ll see the blue mostly. Varies in different locations under various conditions. Light is least scattered in light of low frequencies. Low frequencies = red, orange, and yellow2. Size of clusters determined the scattered cloud color. Water molecules resonate somewhat in the visible red, which causes red light to be a little more strongly absorbed in water than blue. Red light is reduced to one-quarter of its initial brightness by 15 meters of water. Very little red light in the sunlight that penetrates below 30 meters of water.
