What is the Doppler Effect? On this explainer, Neil deGrasse Tyson and comic co-host Chuck Nice break down this famous phenomenon in the electromagnetic spectrum and how we use it in both science and our daily lives.

What’s the sound of a car zooming by? We explore the change in frequency with distance. Find out how this effect applies to light and what “redshift” is. What do we learn from a Doppler shift? Learn about how the radar speed guns that traffic cops use work and possibly how to get yourself out of a speeding ticket. Discover the many ways we use the Doppler Effect every day!
