Is there really gold at the end of a rainbow? And can you even get to the end of a rainbow? In this BrainPOP UK movie, Tim and Moby give you a lesson in rainbows and visible light. You’ll learn about white light, the seven main colours of the rainbow, and waves and frequencies of light. Find out what prisms are and how they refract light to create colours, plus other ways rainbows form in the natural world. You will also discover whether rainbows are real objects or just optical effects! You’ll never look at a rainbow the same again!
