We're cutting through the physics and the fundamentals of sound waves and its propagation this week.Below is a download link for the notes for outcome 1, and also some links to demonstrate what i am referring to with particle motion etc...
Outcome 1 notes link....
Particle motion link...
particle motion clips
I have trolled my way through a vast vast selection of dreadful video clips to find a few that would'nt be classes as weapons of torture. Here's a few from the torture pile….
Now to the real stuff….this is a wee cracker about particle motion ….
Sound pressure propagation….
Compression and rarefaction in air…..
More on particle movement in propagation….
Here is a great wee link to a video clip from the bbc….
