Quizplus · Accepted Answer

In a primary rainbow, the light is reflected once inside the water droplets, while in a secondary rainbow, the light reflects twice inside the droplets. This causes the light to disperse more, resulting in a dimmer appearance. Therefore, a primary rainbow is brighter than a secondary rainbow because there is one less reflection inside the water drops.
