Dispersion The Rainbow and Prisms – College Physics. The refracted light is emitted perpendicular to the direction of the dipole moment; no energy can be radiated in the direction of the dipole moment. Thus, if the angle of reflection Оё 1 (angle of reflection) is equal to the alignment of the dipoles (90 – Оё 2), where Оё 2 is angle of refraction, no light is reflected., Definition Of Dispersion Of Light . The process of splitting of white light into seven colours is called dispersion of light. Example: Formation of Rainbow during a cloudy day. Step 1: Sunlight passes through the raindrops. Step 2: Some of the sunlight is reflected and some other part is refracted (passes into the water droplets). Example: Through a window glass light reflects as well as refracts..

Common optical phenomena are often due to the interaction of light from the sun or moon with the atmosphere, clouds, water, dust, and other particulates. 1. The separation of a beam of light into its component colors, i.e. into its component wavelengths, so that a spectrum is formed. It arises because of the variation of the refractive index of the transmitting medium with wavelength. It occurs in a lens or prism, causing chromatic aberration.It also occurs to a small extent in the Earth's atmosphere, producing atmospheric dispersion.
The formation of rainbow is based on the process of dispersion of light. It is the most enchanting example of dispersion of light which takes place naturally. Usually a rainbow of seven colours is seen in the sky just after the rain when the Sun is shining. The essential condition to see the rainbow is that the observer must stand with his back Light exerts physical pressure on objects in its path, a phenomenon which can be deduced by Maxwell's equations, but can be more easily explained by the particle nature of light: photons strike and transfer their momentum.
