scattering effect of light Tyndall effect

As in the case of the refraction oflightthrough prisms with nonparallel sides, the refraction oflightat two boundaries of the droplet results in thedispersion of lightinto a spectrum of colors. The shorter wavelength blue and violetlightrefract a slightly greater amount than the longer wavelength redlight.Aclear cloudlessday-time sky is blue because molecules in the air scatter bluelightfrom the sun more than they scatterred light. When we look towards the sun at sunset, we seeredandorangecolours because the bluelighthas been scattered out and away from the line of sightArainbowis a meteorological phenomenon that is caused by reflection, refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky. It takes theformof a multicoloured circular arc.Rainbowscaused by sunlight always appear in the section of sky directly opposite the sun.
