Loved the concave spherical mirror animation. The visuals helped me understand how the pinhole and mirror worked with the camera. Great video! Excited for part 2!!

3:12 An exception could be when you're driving down on a hot day, and they air just looks weird, light you can see squiggly line things; I honestly do not know how to describe that

Yup, that's a perfect example! It's called a mirage. As the hot asphalt heats up the air above it, that layer of air becomes significantly warmer than the air above it. This generates a density gradient, which causes the resulting refraction to become visible.

In your next video, could you film a deep bass subwoofer? Maybe in slow-motion, if possible?

Incredible! Can sound waves be modelled like this, too? I mean after all, they are some compressions and rarefactions, and so probably, we can see them with schlieren. What do you think? Can't wait for Part 2!

So yes, you can visualize sound waves! If you wanted to capture sound without any sort of intervention, you would need either need an extremely expensive high-speed camera or an extremely expensive high-speed strobe, since the speed of sound is far beyond what a normal camera shutter can capture. But another (cheaper) way is to create a standing wave by reflecting sound off some type of barrier, so that the peaks and valleys appear locked in place instead of a blur that's literally moving at mach 1. That could be filmed with a regular camera.

This is what happens when millennials post-millennials take on the role and justification and explaining something like physics. It's so much more well understood in this time of age that it is only going to propel people's inept expression. So imagine basically homies, dawgs nailing the structure of science. But still continuing down that path. This is what it is propelling. The means towards justification. Great job on the presentation. Thank You.

Great video! I am looking to make a set up like this, but I am have trouble with finding a proper mirror. I need one with a long focal length (at least 900 mm), like you shared here, but it looks like the ones you shared are no longer available. Any suggestions? Thanks!

You can see schlieren with your unaided eye when you open up your car on a really hot day, as the hotter air from inside your car escapes into the cooler air outside.
