The Physics of Sound

This is a powerpoint I made for our reference. It contains the basic physics of sound - key words, how it travels, etc.

It could also be used as the slide for the first lecture.

I do not own the pictures used in these slides. Most of the information was taken from http://www.physicsclassroom.com/class/sound/.

    Great slides, but I just have some few things to add.
    **Slide 1: There are other waves which are longitudinal besides sound waves, for example, some electromagnetic waves. I love one of the definitions on one of the readings the Professor gave us: "Sounds are pressure waves of air." You can then go on an explain that they are longitudinal and all.
    **I like your expansion on the mechanical aspect of sound waves. You could also add that there is no sound in a vacuum or in space coz there is no medium of transfer for the sound. I believe that will give people more understanding

    ***On How Do Sound Waves Work, if I were taking the class and not familiar with sound at all, it certainly would not be very clear to me how I get to hear sound. We might want to revise that material. Yes I do understand compressions and rarefaction, but what's the importance of that in how sounds work? We could check out one of the articles Professor Franklin gave us to read for our first week.

    ***Very nice illustrations on sound representation and sound terminology.

    Good job Julia, we could just work on those things I think, provided everyone else feels the same about that.
