Question

Explain the process of formation of Rainbow in brief?​

Answer 1

Explanation:

Formation of Rainbow :

(a) The beautiful phenomenon of the rainbow is a combination of three different phenomena - dispersion, refraction and reflection of light.

(b) The rainbow appears in the sky after a rain shower.

(c) When light rays from the sun enter the water droplets that act like small prisms, they refract and disperse the incident sunlight.

(d) This light is then reflected internally, inside the droplet and is finally refracted again.

(e) Due to the collective effect of all these phenomena, the seven coloured rainbow 'VIBGYOR' - violet, indigo, blue, green, yellow, orange, red can be seen.

Process of Formation of Rainbow:

• A rainbow is a meteorological phenomenon that is caused by reflection, refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky. It takes the form of a multicoloured circular arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the sun.

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