Why do microwaves have spinning trays? It’s not for a cheesy reason!
This video stitch (@museumofscience @alex.dainis) explains in ASL the science behind microwaves and shows how you can use cheese to see the length of a wave!

ID: A video stitch of a woman explaining the science behind microwaves by placing cheese in a microwave without a spinning tray. The video shows cheese and wave nodes. Scott is on the bottom left signing the captions in ASL. At the end, a white background appears with repeating red text: “The more you know.” The closing video shows white background with blue text: Enjoyed this video?

Transcript: Did you know you can use cheese to visualize the microwaves inside your microwave oven? Line a plate with cheese. Take the spinning tray out of your microwave and place the cheese inside. When you turn your microwave on, an electrical circuit creates microwaves that bounce around inside, filling your oven with energy that heats your food. But because these microwaves are bouncing back and forth between metal walls, they create something called a standing wave, which has nodes where the energy is low and anti-nodes where the energy is high. The high energy spots heat your food well and the low energy spots not so well. You can see these hot and cold spots on the cheese. These are the nodes and anti-nodes of the wave. The distance between two nodes or two anti-nodes is half of the wavelength. So you can see how long a microwave is by multiplying that distance by two. And this is why the spinning tray inside is so important for helping to heat your food evenly.
