Build a Band
Our process:
During this project we were tasked with creating 3 different types of instruments, String, chime, and wind. As for me I had to chime, the first thing I had to do was my blueprint. After that we spent the next week or two constructing our instruments. Finally after many trail and error I finished my hanging chime. And in order to prove our knowledge of how instruments work, we had to present our instruments to the class.

Content:
Frequency:
The number of vibrations per second. Frequency can be found using (f = v/λ), the unit is Hertz. And when playing our instruments, the frequency that the instruments made determined how high or low pitched the notes were.λ
Wavelength:
Distance of one wave crest to crest . The equation for wavelength is λ= v/f. The unit is meters. Waves with shorter wavelengths will carry more frequency and energy than waves with longer wavelengths.
Wave Speed:
How fast waves travel. The equation to find the wave speed is (v= λf) and the unit is meters per second or m/s. Sound waves travel faster through more rigid materials like metal or wood.
Amplitude:
Distance from midpoint to max point of a wave. The unit is m for decibels.
Transverse wave:
Particle motion is perpendicular to the direction of wave motion. Light and everything on the electromagnetic spectrum are transverse waves. Transverse waves do not require a medium and can travel through a vacuum, like space.
Longitudinal wave:
Particles compress and rarefy as wave energy moves along. Sound waves are longitudinal waves. Longitudinal waves require a medium to travel through. Therefore, they cannot travel through space.
Electromagnetic Spectrum:
This is thee range of frequencies and wavelengths of electromagnetic radiation. Waves on the electromagnetic spectrum include, x-ray, gamma rays, light, radio waves.

Overall I liked this project a lot. I think I did a rather good job problem solving and persevering when a problem occurred. I originally planned to make a xylophone using string to make the pipes float for better vibration, but that ended up being incredibility hard to tie. So I ended up making a hanging chime, and everything ended up getting down.
Something I think I could of done better was being more helpful, since I was really focused on just my instrument I didn't get to help my group as much of I would of liked. Another thing I could have done better was communication, I usually only talked with my group when needed, and wish I communication with my group more. Ultimately this was one of my favorite projects and everything turned out just fine.
