But you forgot to say that with the shape and bouncing, high frequencies come back a bit earlier than lows (like a prism with light), making that piew piew sound.
The speed of sound being slower than most people would think is actually one of the coolest things because it’s really noticeable in a lot of things when you know about it
If you wanted the same amount of delay but for the speed of light the well 11,643 miles deep or about 768,414 times longer that that well. Also if you were to yell into that super deep well you would expect the echo in about 30 hours (15 hours one way)
@@petevenuti7355 fiberoptic cable is shockingly light 1 mile is only 3-5 pounds. However there is a lot of it. On the low end it could weigh 34,929 pounds or about 17.5 tons. On the high end it could weigh 58,215 pounds or just over 29 tons with the in-between weight of 46,572 pounds or 23 tons
When i was luttle there was a construction site for a road 100ft fro my house and my feiend and i would throw rocks into a blue llastic pipe going through the groung and it would make this sound but way better
Not just any ordinary well though, has to have a metal pipe instead of just cement or concrete whatever its usually. But whats the banana doing there next to the coin? 😂
per second squared. It's a rate of acceleration not speed. In other words it's a rate of change in speed. It's going faster each second then the second before.
For speed you use a unit of measurement like miles per hour or MPH but to describe acceleration you not only have to specify a speed at which you accelerate but also a duration so like "If you step on the gas pedal you will be accelerating at a rate of 5 MPH for every second you hold the pedal down" or 5 MPH/s, miles per hour per second the pedal is held down but they're measuring the speed at which the coin falls so instead of MPH per second it's seconds per seconds or for every second the coin is falling it speeds up at X inches, cm, ft, whatever unit you want to use per second per second.
Neat. Takes me back to dropping rocks down sealed, deep mine air vents back home. Always wondered how many animals died in those mines by falling into those vents?
Or do a little bit of thinking and convert them yourself; like me and anyone else that lives in an imperial country has to do, when you guys don't include an imperial measurement.
How many coins would need to have been dropped before the sound INSTANTLY returns? Don't let your imagination run wild... there is an answer. *** and no, I don't have it.
i think it's really cool how the well itself has a resonant pitch that's based on how many times the wavefront can move back and forth through the well, rather than circulating air currents like a normal resonant cavity, i would love to see you probe its resonance, put a sine wave generator's speaker on the top grate and then cover it with a pane of glass and then slowly sweep the sine wave from 20hz to 10khz, see if you can find a frequency that breaks the glass, that would be neat or if it's like an exhibit and you don't want broken glass near the well, then just use a bit of sheet metal or a trashcan lid or something, or just leave it open because the grate does reflect it a little bit
Despite living all my life, I have never heard the rate of falling due to gravity expressed as feet per second. I had to look up a conversion to make sure 32 feet per second was about 9.8 meters per second. It's about 9.75 meters per second, so close enough.
You dont need a well to create that ricochet or bird chirp sound. I find the best spots are when you find a 90° bend in a big brick wall, and stand inside that corner and clap
Funnily enough my football field at my school makes a very similar sound I would always hear it every time we would clap to begin a play or during our practice
