Draw a labelled diagram to explain the formation of rainbow in the sky . Class 10

Answer» When a beam of white light enters a prism, it gets refracted and splits into its seven constituent colours. This splitting of the light ray occurs because of the different angles of bending for each colour. Hence, each colour while passing through the prism bends at different angles with respect to the incident beam. This gives rise to the formation of the colour spectrum.
Rainbow is formed after three phases first internal reflec5ion refraction dispersion
Rainbow is formed by water droplet .
