Sound

Audio Database By: Aarkentechnologies 

Summary: Sound is a mechanical wave that allows us to hear various noises. Sound is a longitudinal wave meaning instead of going up and down, it compresses, and decompresses. Sound is also a type of energy, meaning that it can be used to manipulate matter, different sounds exist because of the fact that they manipulate the air around it. The frequency of the wave is directly related to the pitch of the sound, meaning that the louder the sound, the larger the frequency.

SP5: Using mathematics and computational thinking
We had to use various different types of math to find out about different properties of a wave. We had to do various measurements on things like the distances between two troughs, and the distance from a trough to the top of the wave. We used these measurements to figure out things about the wave, like its frequency, its wavelength, and the amplitude of the waves we measured.

Energy and Matter
Sound relates to energy and matter, because sound itself is a form of energy, you can use sound and the vibrations that it creates to manipulate matter. Matter is also related to sound because it is a mechanical wave, meaning that it cannot exist without matter, because it has to travel through matter to exist, specifically travelling through matter in the form of vibrations.
