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.

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:
