How to hear light!
In this video we investigate whether it's possible to hear light. Surprisingly, the answer is yes, and it's easier than you might imagine. The key is to make use of a photo-acoustic transducer, and it turns out that these are surprisingly simple to create! If you like this video, please share it with others who you think would find it interesting (and by all means subscribe!) You can also support this channel through Patreon: / allthingsphysics . This project was supported, in part, by Dickinson College, and was inspired by a Physics Teacher article written by Manfred Euler, Kurt Niemann, and Andreas Müller (https://doi.org/10.1119/1.1321818 ). An online version of this article is available at https://hearinghealthmatters.org/wayn.... A big thanks to Scott Boback, Jeff Forrester, Anna Gnagey, and Anastasiia Halchenko for listening to a glass jar. I am also indebted to my advisory panel (Lars English, Jeff Forrester, and Brett Pearson) for helpful comments on an early version of this video. And as usual, I'd like to acknowledge my Dickinson colleagues for supporting my efforts, and to Jonathan Barrick for constructing several useful pieces of equipment for this project. Lastly, thanks to Rob Dean for helping with the beautiful SEM image of the light bulb filament! The video I highlighted that discusses hearing light is from The Action Lab ( • Can You Hear Light? The Audio-Modulated Li... ), and I want to be clear that I'm not being critical. I love what he does and support anyone out there who is trying to demonstrate how awesome science is! There's a ton of great stuff on his channel, so check it out and learn something new! Music for this video: "Shadows of the Mask" by Theatre, a progressive rock band from the Seattle-Tacoma area that was active in the 1980's.
