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.

Explanation:
Opposite Direction of Rainbow:
- The statement that a rainbow is always formed in a direction opposite to that of the Sun is correct.
- This is because the sunlight enters the raindrop, undergoes reflection inside the drop, and then exits the drop in the opposite direction it entered.
- This causes the rainbow to be formed in the opposite direction of the Sun.
Refraction and Dispersion of Sunlight:
- The statement that sunlight undergoes refraction and dispersion in the water droplets to form the colors of a rainbow is also correct.
- When sunlight enters a water droplet, it is refracted and dispersed into its component colors due to the different wavelengths of each color.
- The light is then reflected inside the droplet and exits, creating the beautiful colors of 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.
