In this project we had to design 3 instruments; one wind, one chime, and one string. We used various types of materials to find the sound that resonates the best to make the clearest noise to our audiences ears. Below is a google docs made by our group explaining the fundamentals of how each instrument works and multiple charts explaining everything.
Wavelength: Wavelength is the distance from any point on one wave to the same point on the next wave. It can be calculated using the equation: wavelength =v/f
Frequency: Frequency is how many vibrations a wave has in a period of time. Frequency is measured in Hz, which is waves per second. It can be calculated using f=wave speed/wavelength, or f=1/period.
Wave Speed: Wave speed is the speed at which a wave travels. It is calculated by the formula wave speed=D/t, or wave speed = f/wavelength. Wave speed is measured in m/s.
Period: Period is the amount of time between vibrations in a wave. It is measured in seconds. Period can be calculated using the equation: Period =1/f.
Amplitude: Amplitude is the distance from a wave's equilibrium to it's crest. It is the volume in sound waves. Amplitude is measured in meters and there is no formula because it is just a distance.
Transverse wave: Transverse waves travel in one direction, and the direction they vibrate in is perpendicular to the direction they travel. The electromagnetic spectrum consists of transverse waves, which is made up of visible light, ultraviolet, infrared, x-ray, gamma, radio, and microwave. Transverse waves are faster than alternative waves and can also travel through a vacuum.
Longitudinal wave: Longitudinal waves are the second type of wave. Their direction of travel and vibration are the same. A longitudinal wave compresses and expands whatever medium it travels. An example of a longitudinal wave is a sound wave. Longitudinal waves travel slower than transverse waves. Since they need a medium to move, longitudinal waves cannot move in a vacuum, such as space. So whenever you watch a movie, and there is an explosion in space, and you hear it, they are lying to you. True story.
Reflection
In this project I feel there were lots of thing I did well and also somethings that didn't go as well. First off, to things that I need to improve on is time management and getting distracted less easily. In all these projects it seems time management is one that consistently comes up. We felt a few days into the project that we were well ahead of everyone and then when the deadline started coming closer we knew that we would be screwed for time. We need to come up with a work schedule from now on and consistently keep a record of what we have done and need to accomplish that day. Getting distracted also ties into time management as well because if you are distracted a lot you wont get what you need to do done. Two things I did do well on was communicating with my group mates about problems that we need to fix and fully understanding the concepts in the project. When we were doing work I communicated with my group mates Diamon and Ryan about what we needed to do on the instruments. Most of the concepts being taught this year I have fully understood and this project was definetly one I grew on throughout the time and feel this could be something I see myself in the future doing.
