About
We made three instruments. One had to be wind, one string, and one chime. We made a bass, flute, and chimes. They could all play 8 notes. In a single octave.
Concepts
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 tranverse waves, which is made up of visible light, ultraviolet, infrared, x-ray, gamma, radio, and microwave. Tranverse 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.

The chimes were very simple and easy to make. The bass took a while to assemble and the wire was very taught. This caused the neck of the to start to bend. We had to reinforce it with wood on the back to stop the bending. To keep the screw taught we tightened a screw the wire was wrapped around. The flute was by far the hardest to make. The angle of the mouthpiece and the spacing of the notes made it hard to make. We also struggled to figure out wether to close the hole near the mouthpiece. After about 5 flutes we finally got it to sound good.
