Understanding Rainbows and Light

The video tutorial explores the formation and observation of rainbows. It begins with an introduction to clouds and rainbows, followed by an explanation of how prisms break white light into colors. An experiment is demonstrated to show how rainbows can be created using a glass of water, a mirror, and a torch. The video then identifies the colors of the rainbow, known as VIBGYOR. It explains how rainbows are formed by raindrops acting as prisms and discusses the unique nature of rainbow observations. Finally, it highlights that rainbows can be seen in various conditions, not just rain.
