Some of his explanations are a bit inaccurate/misleading though. For example, the refractive difference between mediums isn't actually due to density, although they are related. And the same goes for sound through a medium. Additionally, when he explained how the "sound beam" works, he said it uses pressure waves to propagate, but that's what literally ALL sound is, it's not special to this. And the generator of the waves is absolutely the source of said sound. The source of the waves IS the source of the sound. All waves need a source, and sound is no exception. It doesn't just materialize from the aether.

@The Action Lab Would have been cool if you calculated the focal point of the balloon to get maximum sound amplification. As for the hypersonic sound laser, I can imagine creating a device that accurately measures how far apart two people are. One person could be 10 miles across a lake from someone else, and shoot the sound laser at the exact same time as a light laser. The person across the lake sees the laser light immediately, and hears the sound 50 seconds later, which tells him the other person is about 10 miles away. That would be cool!

I found this experiment really interesting, I think you should consider that in the case of light, the wave length is way smaller that the lenses, so I recommend to repeat it with a weather balloon and maybe add some distance between the sound generator and the sensor. After all, light experiments mostly use planar and coherent laser like waves. You could use dry ice to obtain the CO2 and use a shotgun mic if you have one. The idea is grate, keep the good work.

Thank you Action Lab, *very cool*

Also, you could take a page from RF and make a phased array with line delays or phase shifters in the frequency range of 20 Hz to 20 KHz.

I've watched several videos, and i apologize if you have covered this already, but, it would be cool to show people how the most basic forms of microphones, speakers, and amplifiers work... and how you can use a laser passing through glass, focused on a simple photoresistor, connected to audio equipment, to record sounds with a laser... i think ive heard the cia or fbi building is actually a building within a building to keep spies from hearing inside because of this simple technology... youre the guy to bring these examples to screen! upvote so he sees this, if youre interested!

In the Seattle Space Needle, they have one of those devices for you to hear the explanations about the view. I even recorded a video of that when I went there in 2011.

Great, now I can watch whatever I want behind the desk not fearing other will hear it.

Best experiment

You can also focus sound with a parabolic dish. In our local science museum they have a display that has two large 6-8 ft parabolic dishes that are about 50-60 ft apart. If both people are standing in the right spot you can hear a whisper at that distance.

We had these things on the ship i was on in the navy that looked like a thick satelite dish. If you pointed it at someone and pulled the trigger it projected sound directionally at them. This results in a serious ammount of physical pain. It can burst your ear drums if it is held on you long enough at full power. It sounds like a very high pitched reverberating squeal.

So interesting

What if 2 sound were directed through each other. Would they have some kind of interference at the receivers end ?

Air particles are very heavy as compared to light particle it is very interesting to study about the ratio of the angles by which they bend during refraction in different materials and for different wavelengths.

So in the future we may have surround sound systems that can track your ears and direct the sound? others in the same room wont hear it? that would be a cool invention

I wish this guy was my science teacher in school

@Acoustic_Theory

A horn speaker confines the radiation angle of sound, but the dimensions of the horn mouth must be large enough relative to the wavelength to exert pattern control and not just create edge diffraction. Think of a straight pipe having the diameter of the sound source: if you use a small source (such as 1"), most audible frequencies will diffract when they reach the end of the tube, because of the sudden change in radiation resistance (forcing the wave to expand in directions not parallel to the horn wall), and the effective radiation angle will be close to 180 or even 360 degrees in any plane crossing the axis. To constrain the radiation angle to smaller angles while having a mouth that opens to be large enough to control the radiation angle, the horn will need to be exceptionally long, even infinitely long. If you make the sound source tens or hundreds of times larger than the wavelength it is producing, then it will begin to exhibit off-axis self-interference, which becomes more intense as the dimensions of the isophase source (think of a flat piston) are increased, producing coherent summation only in the axis of radiation with minimal spreading, but these sources can become impractically large to transport or mount. (Look at the Meyer Sound SB-3 "sound beam" - it is an array of dome tweeters creating a sound source that is substantially planar, substantially continuous, and substantially isophase.) An array of ultrasonic transducers is able to create narrower beams of sound than a horn can produce, and because even a radiator of practical size becomes large relative to the wavelengths of ultrasound that it is producing, it is able to make use of off-axis self-interference to create a narrow beam at distance. Because ultrasound is being produced, it cannot be heard. It needs to contain modulation content that occurs at audible frequencies in order to be perceived by the ear. So the ultrasound needs to be demodulated somehow, and it does that by interacting with a high impedance surface, causing the ultrasound energy to be reflected in a non-isophase manner and mostly destroyed, but the residual variation in pressure is demodulated as audible sound. In a Class-D amplifier, this is done electrically by passing the modulated ultrasound signal through a reconstruction low-pass filter, but in the physical domain anything providing a reactive low-pass effect can demodulate the ultrasonic carrier, causing the resultant pressure to contain only audible content below the low-pass corner. Once the concept of demodulation is understood, a number of methods for achieving audible transmission become apparent. You can employ frequency modulation (resulting in amplitude modulation of another ultrasonic difference tone between a steady ultrasonic carrier tone and a sliding ultrasonic carrier tone as the carrier), amplitude modulation, or pulse-width modulation. You can use mechanically transmitted pressure waves, or you can use other forms of energy to do this also - radio frequency, microwave frequency, or even light, though the power needed to produce air movement can be great enough to cause injury to a subject, so you would need to be careful. This power, modulated at audible frequencies so the demodulated signal consists only of audible content, can be used to produce audible sound. This phenomenon of energy demodulation is likely what caused American diplomats in Cuba to perceive harsh-sounding audio as they awoke inside their domiciles while their brains were being damaged using a directed energy weapon, causing people in the public to suspect that an "acoustic weapon" was at work; in reality, sound (acoustic pressure waves) would not be able to pass through the walls of their living quarters without being strongly attenuated, but radio frequency energy can pass through walls, and if its modulation contains audible content, then the person or animal subject will experience audio while the rest of the energy is being dissipated in their body in another way (such as frying their brain).

I wanted to ask that can light push any type of particles

You also could've used sulfur hexafloride and if you did would it make to result better?

Well is it same as connecting two plastic cups with string(thread) using one cup as transmitter and another receiver? Because it travel through air(rarer medium) in cup first and then string(denser) via cups

Big fan! If water is pumped through a circular pipe at a high velocity, would this mimic a gyroscope?

do the lenses curve the light or angle it differently upon refraction? Isn't a curve just an infinite amount of straight angle changes so i guess the light could curve. I'm still a little confused on that. Great video!

There was a set of whisper dishes at the science museum. You whisper into the satellite dish and the person right next to the other dish was the only one who could hear it.
