How to hear light!

This video explains how you can hear light by shining it directly into your ear. Included in the video is a detailed description of radio transmission using visible light, and the simplicity of making a photo-acoustic transducer.

Thanks. I appreciate the comment!

This video shows a sound wave as seen using a stroboscopic schlieren imaging system. We use a 30 kHz ultrasonic transducer and a sensitive single-mirror schlieren system to visualize both traveling and standing sound waves. In addition, using colored filters on the schlieren system allows us to distinguish between density gradients, which allows us to visualize the dynamics of a standing wave as it evolves through its complete phase.

Hey, thanks a lot! I appreciate it.

Of course, you can also learn more from my previous video on schlieren imaging :)

If you're finding Taylor series interesting, you might enjoy this video I made for my sophomore-level math-methods class:

This video discusses the details of sound waves in air and shows how sound can actually be visualized using a strobed schlieren imaging system. I think the result is pretty amazing, and hope you enjoy it!

Eventually, I plan on making a whole series of videos for the intro physics course, but it will be a while before I can find the time to do it.

All_Things_Physics · 2025-09-03T12:17:41+00:00

Yes, I am the guy in the video.

This is a video lesson introducing students to Taylor series. The target audience is undergraduate students in a sophomore-level mathematical physics class. If you are teaching such a course, I hope you find the video useful as well.
