That should be standard equipment in every physics subject. Great setup.

If only we were taught Physics like this back in school 🤦

Bro casually thought my 12 grade physics in a shorts

I like how this is the perfect way to explain how light travels through a camera lens, and why precision in manufacturing them is so important!

[Lex-AAAAA]

Convex, concave. This is what glasses do to help you see better

[ColinTimmins]

I was so fascinated with lasers as a kid in the early 80s, but I never expected light to be so cool 😎

That multi laser tool looks really cool for testing resistances and various educational demonstrations like you did here

[hullinstruments]

Damn this type stuff is what we needed when getting interested in photonics as a teenager. Sure would have saved a lot of time and made learning more efficient over the last fifteen or twenty years

[rubrumvulpespuella]

Thank you for showing optical geometry through experiments, it helps a lot for understanding !

[seaweed]

Nice demonstration, I worked with a optical laser table once for a research project I was doing. What surprised me the most is how perfectly and precisely you need everything lined up for literally anything to work.

[yaoalvin]

A great way to describe and teach the features of a parabola’s vertex. It also means the derivative at that point is 0.

[ALPHAMEGA.]

You're truly deserving to be famous

[sciencetime]

It's cool to watch the beams converging and diverging depending on the lens used. This could be useful in power transmission

[misfit]

Took an optics class where we went over stuff like this, and I did NOT pay enough attention., realizing over the years how optics are hugely important! Can’t wait to see more!

[sebastiangudino]

Really cool demonstration! I would love to see something like being used to explain why pictures come out reversed (upside-down) and the sensor has to reverse it to make it more like what we humans expect

[hoosiers]

Thats actually amazing, learn something new everyday

[gallopingghostofthejavacoa]

And there you have it: the derivative of the curve is zero, there is no slope in the curve of the lens, and the lens is essentially flat

[JustSomePasserby]

The reason the lenses don't do anything in the middle has nothing to do with their depth or local curvature at a point.

It is because the lenses you placed in the middle are reflectionally symmetrical. Since the focal point of the first lens falls exactly in the middle, the 2nd half of the middle lens undoes whatever refraction the first half of it did.

If the lenses were geometrically perfect, the double convex lens should also affect no change.

I love this demonstration. So easy to see what's going on with lasers as opposed to say a torch or bulb
