The Speed of Sound & How does Sound Travel? A Fundamental Understanding

Sound moves incredibly fast! You snap your fingers, and it can be heard almost instantly throughout an entire room. But how does sound travel so quickly? Do you know how sound travels? Also, how does pushing a table relate to sound? This video goes into the fundamental ideas behind sound wave propagation. It uses a thought experiment to help better visualize the movement of particles.

Key Branches from this video are: What is Sound? Understanding the movement of air.
Additional branches are: Types of waves, Ears, Frequency & Loudness,

This animation was my first use of low poly animation. There were a total of 5 main scenes with an intro and an outro. It took me about 5 weeks to make the scenes while rendering at night. I find this topic fascinating because most people don't realize that all your movements and actions take time to propagate to other objects. When you pick up a pencil, you think every bit of the pencil moves together, however that's just not the case. Eventually, in another episode, I'll get into the deformations related to moving and applying a force to everyday things- like when you lean on a counter, the counter height sinks- but that episode will have to wait. If you have any questions or comments, I would love to hear them!

I was a Sonar technician in the US Navy for 12 years, and a firm understanding of sound propagation (in various mediums) is required learning. If only resources like this were available when I was in Sonar school... Thank you

[madafakaniga]

The way you help understanding with using visuals is one step above the learning material i have witnessed so far. Thank you for your education, it's a blessing.

[sanjubhargav]

This is the first comment i have ever written, i really want to let it out of mý heart...that most of the students even at this era is missing subject in practical perspective, and you are bridging the gap from other side of world to me in india and for many others...really feeling fortunate for finding your are replenishing the suggestable channel😘😘😘

[tanjo]

This is a useful, visual aid which has successfully assisted my understanding of the related topic. Good job.

[JosephEudave]

Do you receive donations? I want to help in any way you work.

The low poly style make me focus easier on informations. Greatly prepared! This example with metal rod between earth and moon - I never thought about it from this perspective, very nice and I would love to see more. Maybe how the sound is propagates in space and interacting with obstacles? And the fact you are using the Blender 3D makes it even more interesting. Thank you.

[motivationformuslims]

O My God. This video was fabulous. This is how concepts should be taught at school. You are doing an amazing job at presenting your concepts.

Secondly, correct me if Im wrong, but the distance the steel rod was pushed was lesser on the moon because some energy was lost on the way to the moon due to heat etc.

[brunosousa]

It's something so simple and so complex at the same time. Great simple explanation!

[viren]

Branch Education has given me a different sense of perception! Yes, not just information, but a true feel/experience of what’s really happening!

[iagyetengenuzui]

Woah, im in 8th and this was really easy to learn! my brother is in 3rd and he really understood everything! Ur the bestteacherrrr

[huserinminor]

It’d be crazy to see the math behind figuring out how quickly the force moves throughout the rod while also taking the varying temperatures into account

[sambathkumarguna]

Easy explanation of what is sound way and way travels

[cosfat]

This is a really high quality content and fabulous perspective to the subject. Thanks a lot!

[Slickstaff_Stainpants]

binge watching this entire channel. it makes such clear sense.

[sisyphus]

I love these explanations! Thank you guys so much for making these videos!!

[ultraspike]

Wow unbelievable, way of concept clarification is stunning.
This is how schools should actually teach but what they do is they make us a book worm who mugs up everything overnight and take examinations.

[mfaraday]

I found your channel late.
But now i am enjoying very much.
Wow what a presentation👍

[Hexspa]

This is amazing. Steel is stretchy! I didn’t know.

[Cybernetic]

Started with a video.. end up watching all of your video..
Please make video on how to edit audio using Fourier transform.

This nice video has reminded me the passage below; Id like to share this different point of view of truth:
"If, for example, there is one point on a piece of white paper and two or three other points are jumbled around with it and then someone who already has numerous jobs tries to distinguish them, he will be confused; and if many burdens are loaded on a small creature, it will be crushed; and if numerous words issue from one tongue and enter one ear altogether at the same time, their order will be broken and they will be a muddle.
Despite this being the case, I saw with complete certainty that with the key and compass of HE, although thousands of different points, letters and words had been put in each molecule -and even in each particle- of the element air, through which I journeyed in my mind, NEITHER THEY BECOME MİXED UP NOR DİD THEY SPOİL THEİR ORDER; and although they performed a great many different duties, these were carried out without being confused in any way; and although very heavy loads were laid on each molecule and particle, they bore them in order without lagging or displaying any weakness at all. And I saw that thousands of different words of all different sorts enter and issue with perfect order from what is in effect those MİNUTE EARS AND TONGUES without being mixed up and spoilt in any way, they enter those minute ears and issue from those tiny tongues, and by performing these extraordinary duties, each particle and each molecule declares through the enraptured tongue of its being and its perfect freedom, and through the testimony and tongue of the above truth: THERE IS NO GOD BUT HE, and: SAY, HE IS GOD, THE ONE, and travels among air-clashing waves like storms and lightning and thunder without in any way spoiling their order or confusing their duties. One duty is not an obstacle to another duty. I observed this and was utterly certain.
That is to say, either every particle and piece of the air has to possess infinite wisdom, knowledge, will, and power, and the qualities for being absolutely dominant over all the other particles so that it can be the means of those functions being carried out, which is absurd and impossible to the number of particles, and no devil even could imagine it, or else, and it is self-evident to the degree of 'knowledge of certainty, ' 'vision of certainty, ' and 'absolute certainty' that the page of the air functions through the boundless, infinite knowledge and wisdom of the All-Glorious One, and is the changing page for the pen of Divine Power and Determining, and like a signboard for writing and erasing, known as a Tablet of Appearance and Dissolution, which has the function of the Preserved Tablet in the world of transformation and change.
Thus, just as the element of air demonstrates the above-mentioned wonders and manifestation of Divine unity in only the duty of transmitting sound and shows the impossibilities of misguidance, so does it perform other important duties with order and without confusing them, such as transmitting subtle forces and energy, like electricity, light, and the forces of attraction and repulsion. At the same time as conveying these, with perfect order, it carries out duties essential for the lives of plants and animals, such as respiration and pollination. It proves in decisive fashion that it is a place of maximum manifestation of the Divine will and command..."
