- Statement 1 is correct: A rainbow is a natural spectrum appearing in the sky after a rain shower. It is caused by the dispersion of sunlight by tiny water droplets, present in the atmosphere. A rainbow is always formed in a direction opposite to that of the Sun.
- Statement 2 is correct: The water droplets act like small prisms. They refract and disperse the incident sunlight, then reflect it internally, and finally refract it again when it comes out of the raindrop. Due to the dispersion of light and internal reflection, different colors reach the observer's eye.
- Since it involves the total internal reflection of sunlight, the light is reflected back in the direction it originally came from. Hence you can only see a rainbow if your back is facing the sun.

With reference to phenomena of formation of the rainbow, consider the ...
Explanation:
Formation of a rainbow:
- **Opposite direction to the Sun:**
A rainbow is always formed in a direction opposite to that of the Sun. This is because the sunlight enters the water droplets, undergoes reflection, refraction, and dispersion, and is then reflected back towards the observer. The rainbow appears in the direction opposite to the Sun due to the way light is reflected and refracted within the water droplets.
- **Refraction and dispersion:**
The sunlight undergoes refraction and dispersion in the water droplets to form the colors of a rainbow. When sunlight enters a water droplet, it is refracted, or bent, at different angles depending on its wavelength. This causes the different colors in the light spectrum to spread out and form a rainbow.
Therefore, both statements are correct. A rainbow is indeed formed in a direction opposite to that of the Sun, and the sunlight undergoes refraction and dispersion in the water droplets to create the colors of a rainbow.
