    We use cell phones everyday. We look at our phones constantly. Iphone users look at their phones 3x more than normal phone users.

    The cell phone uses circuits to power it. It uses waves from cell towers so we're able to call and send messages and stuff. The screen gives off light waves which is what we see when we look at our screens.

    We take advantage of technology. We use things without thinking. We learn how to do things fast, but we don't really know how it all works,

    Music is great. It's the thing that everyone likes whether they're into making it or just listening to it. Everyone at one point or another likes music to some extent. Music is a rather general term because there is so much to music. There is composing, performing, audience, and so much more.

    There is so much physics in music, especially in the performing part with all the different instruments. The guitar for example, uses strings and whatever material is used to make the body, usually wood, to make the actual instrument. Than the strings are attached, aligned, and tuned to that when you press down on the strings on the different frets you change the wave lengths of the standing waves and create different notes. This goes for all string instruments. Other instruments such as trumpets and what not use valves instead of strings to change the wavelengths of the standing waves. How hard you strum a guitar or blow in a trumpet changes the amplitude which is how loud it is.

    Musical instruments use a lot of waves and magnetism depending on which ones they are. Guitars (acoustic) use waves which reflect off of different surfaces so we can perceive it. Electric guitars get plugged into guitar amplifiers which are composed of amplifiers, and speakers which are made with magnets and coils.
