Vedclass · Answer

(B) The formation of a rainbow is a natural phenomenon caused by the dispersion of sunlight by tiny water droplets present in the atmosphere.$1$. Refraction: As sunlight enters the water droplet,it bends due to the change in medium.$2$. Dispersion: The white light splits into its constituent colors $(VIBGYOR)$ inside the droplet.$3$. Total Internal Reflection: The light rays strike the inner surface of the droplet and are reflected back.$4$. Refraction: Finally,the light rays refract again as they exit the droplet,reaching the observer's eye.Therefore,the correct combination of phenomena is refraction,dispersion,and total internal reflection.

Which of the following phenomena of light are involved in the formation of a rainbow?
