Music is such a big part of my life. I honestly cannot imagine what life would be like without it. Suprisingly, I guess I have physics to thank for the music that makes life so great. Without waves, more specifically sound waves, we wouldn't be able to hear music. Or really any sounds.
Sound waves are longitudinal waves. In a longitudinal wave, the medium is moving in parallel of the direction that the wave is going. They're also mechanical wave. That just means that they require a medium to travel through. For example, sound cannot travel in space.
When there are sounds around you, the waves travel into your ears. They vibrate your eardrum which then causes bones in your ear to vibrate. The sound waves are eventually converted into electrical nerve impulses which get sent to your brain. Once registered by your brain, you are able to recognize your favorite song playing.
