Formation of rainbow involves all three phenomenon:

• total internal reflection.

Explanation :

Formation of Rainbow :

• The beautiful phenomenon of the rainbow is a combination of three different phenomena - dispersion, refraction and reflection of light.
• The rainbow appears in the sky after a rain shower.
• When light rays from the sun enter the water droplets that act like small prisms, they refract and disperse the incident sunlight.
• This light is then reflected internally, inside the droplet and is finally refracted again.
• Due to the collective effect of all these phenomena, the seven coloured rainbow 'VIBGYOR' - violet, indigo, blue, green, yellow, orange, red can be seen.
