Vedclass · Answer

(B) rainbow is a natural spectrum appearing in the sky after a rain shower. It is caused by the dispersion of sunlight by tiny water droplets,present in the atmosphere. These water droplets act like small prisms. They refract and disperse the incident sunlight,then reflect it internally,and finally refract it again when it comes out of the raindrop. Due to the dispersion of light and internal reflection,we see a spectrum of colours in the form of a rainbow.
