Which of the following phenomena is responsible for the formation of a rainbow?

Which of the following phenomena is responsible for the formation of a rainbow?

Step 1: Understand that a rainbow is a colorful arc seen in the sky.
Step 2: Know that rainbows usually appear when it is raining in one part of the sky and sunny in another.
Step 3: Recognize that sunlight is made up of many colors (like red, orange, yellow, green, blue, indigo, violet).
Step 4: Learn that when sunlight hits a water droplet, it bends (this is called refraction).
Step 5: Understand that as the light bends, it spreads out into different colors (this is called dispersion).
Step 6: Realize that the light then reflects off the inside surface of the droplet and bends again as it exits, creating a circle of colors.
Step 7: Finally, see that we only see a part of this circle, which appears as a rainbow in the sky.
