Hurrah, we come to the end of the module! We have understood how rainbows are formed in this module.We saw that we need sunlight as it is the source of light. We need water from rain to disperse the light. To see the rainbow, we must be located between the sun and rain.We also saw that rainbows are circular, and have red at the top and violet at the bottom.
