If the mirror is not very quality..and it is 50 mm dia, 150mm FL, can this mirror produce schleiren effect?

Great Video. At about 5:50, when you make fire reaction travel up the gas (loved the chain reaction visualization), I guess it would show best the dynamics with the use of a IR camera. As we can see thanks to this arrangement, the fire starts and propagates without emitting "flames" (in the visual spectrum). You and people like you make SVfrom worth using and a better place, thanks.

K, he said 1800mm focal length. I'm guessing ~300mm diameter?

I have a supersonic nozzle that we have made (converging diverging). With the naked eye you can actually see the shock diamonds in the air flow. I would be happy to allow you to make a video showing supersonic flow in compressed air. We could send you the nozzle (we would like it back) and you would need at least 40 psi and a large air compressor capable of 200 cfm. Or we would be happy to show you a demo in person if you would like to bring your photography equipment and setup in our facility. We have plenty of compressed air.

How about a large diameter (15mm) clear glass neon tube? This would be filled at pressure of 8 mm/hg - atmosphere pressure is 760 mm/hg. Let me know, I'll make a sample tube for you as I make neon signs.

I wonder if you ran some edge detection algorithms on the smoke and smoke lines with some parametric curves, could you derive the differential equations that model flow curves (like navier stokes)?

To see a sound wave you could protect the mirror with trasparent glass and light a firecracker. It's a try that could easily fail, but the footage might end up to be interesting anyway, give it a chance!

you saying "rainbow schlieren" made me wonder how it would look to use 6 colors of triangle (sorry indigo) converging on the focal point instead of cyan and magenta. I only go with 6 because it would keep a horizontal separation between ROY and GBV, commonly considered the warm and cool colors respectively

Its funny that everyone who starts trying to explain how this works, ends up trailing off into the demonstration again without really ever telling anyone how it works. I understand it, but I'm positive there are thousands of people who end up thinking they just never will.

The camera in shot appears to be a Panasonic Lumix (probably a G5 or G9) which can only (to my knowledge) handle 20fps. I have a G9 so naturally curious. What camera was used to obtain 2000fps, or did you fall into error when intending to refer to 20fps? [I use my G9 for microscopy]

If theoretically you used a gradient colored filter (film), say a rainbow gradient. Would that allow for colored Schlieren effect? RGB?

Looking for sounds, use a mini speaker playing a metronome type of rhythm with different frequencies. Then take two lit candle wicks on both sides of the speaker to act as a tuning fork.... Oh.... Wait.... I guess you could look at a tuning fork through it. Well the speaker is still in the table.

Paraboloids are difficult to work with because the only way to measure their properties is to measure what you can and deduce the rest. It's a shame required engineering math for non-engineering majors stops with 2D conic sections. When things don't get interesting until you start using 3D conic sections to affect sound, light and other waves.

A little hard with your setup but a neat way to see sound could be to setup a speaker/audio monitor in front and if it's loud enough you can see and feel the pulse it let's out. Probably would annoy any neighbour's but might give some interesting results lol
