Answer» s_Guru_DevDear student,Rainbow is formed due to following reasons:Refraction, Dispersion of WHITE LIGHT , total internal reflection.Essential condition for formation of rainbow:1. Presence of raindrops2. To view rainbow, sun should be at your back.Formation:The rays of sunlight, enter the DROP near its top surface. At first refraction occurs , then white light is split up into & colours , violet most deviated and red least.Reaching the opposite side of drop each colour is refracted back into the drop because of total internal reflectionarriving at the surface of the drop , each colour is again refracted into air.We observe the rainbow when we view in between 42-20 DEGREES.
