In physics, sound is a vibration that typically propagates as an audible wave of pressure, through a transmission medium such as a gas, liquid or solid.

More sound experiments that will revolutionize engineering and music forever. (And they all utilize similar concepts from my previous posted videos)

This experiment is simple to do and cool to look at. By placing a thin rubbery membrane over a speaker and attaching a mirror to that membrane-speaker combo, you can shine a laser at the mirror as it plays to change the pattern of the laser. By varying the frequencies, the laser will ultimately show you the complexity of a sine wave

A cool experiment that uses a wave driver and various frequencies to move sand into cool patterns. The sand pattern essentially show nodes and anti-nodes, where the nodes are the areas in which have no sand (vibrating) and the anti-nodes with sand (not vibrating). All-in-all, cool to watch, terrible to listen to.

This speaker is great for pranks because it utilizes many smaller speakers within it to intentionally cause interference with each other. Using ultrasound, the many speakers within the larger one, interfere with each other and force the air around it to generate sound in a straight line making it only able to be heard when standing in front of it!

This Kundt's tube experiment utilizes differing frequencies in order to generate high and low pressure fields within the closed tube. Each frequency, when set at a specific amplitude, raises the styrofoam balls and shows the viewer the nodes and anti-nodes (or vibrating and non-vibrating areas) of the sine waves.

What is Sussle?

Sussle is the first, open visual encyclopedia. Anyone can use it.

What's a visual encylopedia?

It has beautiful images and viral videos that are way more fun than reading all the text in traditional encyclopedias.

5 reasons you should add your own images and videos:

  1. If you found Sussle interesting, then give back by adding something interesting for others.
  2. Help others learn in a fun way.
  3. Make someone else interested in this topic laugh or say wow!
  4. Become internet-famous as people like and share your post.
  5. It's super easy, so it won't take more than a minute.
