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.

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!
