Only the edges from up are coated with iso-alcohol? Or the bottom also?

We squirt it onto the felt strips that line the top of the chamber. Some of it will inadvertently spill onto the bottom, but most of it should be at the top.

Great video 👍, just one thing to add to the ping pong ball experiment that's overlooked all the time, the jet of air released into the atmosphere and levitating the ball has a static pressure equal to atmospheric pressure or the pressure above the ball would cause the ball to be forced towards the dryer and not levitate.

What determines the length or shape of the antenna
@NatSciDemos10 күн бұрын
The length is one half the wavelength of the transmitted signal. For more details, see sciencedemonstrations.fas.harvard.edu/presentations/radio-wave-properties

Amazing video, thank you for sharing that I really wanted to see this experiment of 90 degree sound beams. Is there a video where the Troboscope is at the same frequency and both transducers are working but you lower or increice the frequency of one of them only. Im supper qurious to see the pattern in this case.
@primeradianttechnologies3085Ай бұрын
Hi tehre this is very interesting Experiment and thank you for sharing it. Could you please tell me if the Stroboscope beam of light is perpendicular ti the sound waves. Im assuming that it is but wanted to make sure if that is correct.
@NatSciDemosАй бұрын
The direction of travel of the sound waves is perpendicular to the travel of the light from the mirror.
@primeradianttechnologies3085Ай бұрын
@NatSciDemos Yes thank you.I make quick research to see how exactly Schlieren set up work and that make sense My next question would be what if the light source is replace it with sound. When light frequency is lower this create the illusion of forward motion, but if that lower frequency is sound too, perhaps won't be illusion but directional force?

So was this test done at 100 watts or less?
@NatSciDemosАй бұрын
Much less than 100W, because the input coming to the amp from the oscillator is very low (the knob is turned down almost all the way). The type 47 incandescent lamp in the dipole receiver is rated for 1W, but we keep the signal well below this level to prevent the lamp from burning out. See the link in the description for more details on the setup.

The near-field effect in the light may have been from the alternating magnetic dipole moments of the charged particles inside the antenna inducing a current in the mercury vapor inside the fluorescent bulb. Some fluorescent lamps, in particular a type of induction lamp, utilize this principle. The fixture typically contains a coil with a high-frequency AC potential powering it, and the bulb is simply glass filled with argon, mercury, and the phosphor coating. No electrodes, so the usual “sputtering” effect of the typical electrodes (that leads to the death of the bulb) is absent. Very interesting!
@1833-j4gАй бұрын
This is an excellent and very concise demonstration! Also, how many volts is coming from the amplifier?
@NatSciDemos18 күн бұрын
The output of the transmitter is set so that it will just barely "strike" an arc in a 12 inch, 8 Watt fluorescent bulb when it touches one of the ends of the antenna.

Is the absorption wavelength was in IR or UV we will not get any line right?
@NatSciDemos2 ай бұрын
If it's not between 400 and 700 manometers in wavelength then the absorption will be difficult to see with the naked eye, and will require another means of detection.

Try to research Sir the "New Astronomical Theory of Motion". This is all about the forces A, B, & C influencing the earth. It is said there that gravity is a virtual illusion and acceleration of falling object - 9.8/sec squared is a fallacy. Those two balls released at same time were in free space and waiting for the earth to swipe them both back and would normally hit earth (land) at the same time, it is not because of the gravitational pull. A falling object is misconceived to be accelerating since at the first few moments after released it seemed it gradually increase speed falling down. However, this is the due to the inertial effect as an object before released is in high velocity going in the direction of the rotating and revolving earth, thus at the first few instants after released it is still influenced by the velocity of the earth going in the same direction, then it decelerates until the immense curvature of the earth takes it back. Basically, the same with the feather and a coin dropped inside and vacuum both of which lands at the same time.
