Physics of music

Music is a huge part of my life and i never would have thought of the physics involved before this year not just because it didn't matter to me, but because i didn't know anything about it and now i do! Through many videos and lectures, i have learned that when a song is playing, the sound waves that are emitted have many components.

First, the wavelength is the distance from the crest of one wave to the crest of the next one. The frequency is the number of waves that pass a point in each second. The amplitude is the measure of the amount of energy in a sound wave or how tall is is from the middle to the top not the trough to the crest! The crest is the highest point on the wave and the trough is the lowest point.

A pitch is how high or low a sound seems and intensity plays a big part in this too. The greater the intensity of a sound, the greater the amplitude. These waves travel through matter, and differ from light waves because sound waves cannot travel through a vacuum. Sound is a longitudinal wave and is classified as a mechanical vibration! Okay i have to go study for my physics test now!
