=======Discussing Sound======== Previously, we have talked about frequency, tone, pitch, and vibrations in regards to sound.\\ \\ Different Ways of Talking about Sound:\\ Amplitude- how big the wave is in terms of height.\\ Wave Length- D=distance from one wave to another.\\ Frequency- the faster the wave moves, the faster the frequency. Counts the number of "humps/how many waves per second."\\ Pitch- how you hear a sound. Can be high or low.\\ \\ {{:days:winter2012daybyday:winter2012day16:soundboard.jpg}} \\ **In order to have sound, there must be something vibrating.** \\ In Electricity, something moves through a wire, which causes a magnetic field outside of the wire. When you have something vibrating at different frequencies, it causes different sounds.\\ \\ Students experimented with speakers made using wires, battery, and a magnet:\\ \\ {{:days:winter2012daybyday:winter2012day16:cupspeaker.jpg}}\\ \\ {{:days:winter2012daybyday:winter2012day16:potspeaker.jpg}} \\
