Which of the following phenomena of light are involved in the formation of a rainbow?
(a) Reflection, refraction and dispersion.
(b) Refraction, dispersion and total internal reflection
(c) Refraction, dispersion and internal reflection.
(d) Dispersion, scattering and total internal reflection.
Dear student,
Answer: (c) Refraction, dispersion and internal reflection
A rainbow is regarded as one of the most spectacular light shows observed on the earth. Rainbow is a multicoloured arc made due to the striking of light on water droplets. Rainbow is produced after the rain, by reflection, refraction and light dispersion process in droplets of water. All such events develop a light spectrum in the sky are called rainbow. A rainbow is a natural spectrum after a shower of rain(every water droplet acts as a small prism) formed due to the dispersion,refraction and internal reflection of different colours.
