Neil deGrasse Tyson Explains Rainbows

Is there really a pot of gold at the end of the rainbow? On this explainer, Neil deGrasse Tyson and comic co-host Chuck Nice break down the science behind rainbows.

We dive into what makes a rainbow and even double rainbows. Discover what Isaac Newton wrote about in his book of “Opticks”. How did people think vision worked? We discuss a simple experiment you can do with the visual light spectrum at home. How does sunlight interacting with raindrops create a rainbow? What is the end of the rainbow? Is there anything over it? Find out how every rainbow is your own personal rainbow from your personal astrophysicist.
