For this project my group and I were tasked with designing one instrument per person in our group. First my group and I started to think about what kind of instruments we wanted to make and how we would go about making them. We decided we would make a guitar, drum set, and a pan flute. With me choosing to design the pan flute and the rest of my group designing the guitar and the drum set. After we decided what instruments we wanted and created blueprints for them, we went to the makers space and started building them. After around 2-3 build days we had finally finished though and were on our way to finalizing our instruments. Then finally, after we finished building them all we did was tune them slightly to fit the correct notes we wanted them to play and then we had finally finished.
Frequency: This is the number of vibrations (waves) per second Frequency can be found by velocity over wavelength, (f = v/λ) or f=1/T(time). The unit is Hertz or Hz. When playing our instruments, the frequency that the instruments made determined how high or low pitched the notes were
Wavelength: This is the distance of one wave from crest to crest( or for sound waves its compression to compression). The equation for wavelength is λ= v/f, with the unit of measurement being meters.
Wave speed: This is the speed in which waves travel(velocity). The equation to find the wave speed is v= λf and the unit that represents it is meters per second
Amplitude: This is the distance from midpoint to max point of a wave. it is represented with the units m for decibels.
Transverse wave: This is when the Particle motion is perpendicular to direction of wave motion for example an ocean wave. Light and everything on the electromagnetic spectrum are transverse waves. Transverse waves do not require a medium and can travel through a vacuum.
Longitudinal wave: This is when 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 the range of frequencies and wavelengths of electromagnetic radiation. The waves on the electromagnetic spectrum include, x-ray, gamma rays, light, radio, etc. The higher you go on the spectrum the more energy the waves have, which in turn means you have a higher chance of getting cancer from said wave.
Wave particle duality: This is the idea that you can use both a wave or a light model to show the behavior of electromagnetic radiation.
How electromagnetic waves work: These waves work by carrying frequencies that can be heard as music or words, they carry particles of light that we see as color based on their different frequencies. And they are attracted to each other because of their magnetic properties. Cell phones also use waves to communicate information to each other. The messages are sent via radio waves that are being transmitted from the receiver to the receptor back and forth.
Ionizing Vs. Non-ionizing: Non-ionizing radiation has less energy than ionizing radiation, therefore it cannot remove electrons from atoms meaning it is far less likely to cause any cancer. However Ionizing radiation has a lot of energy and has the ability to strip electrons from atoms. Which in turn means it can cause cancer, and in certain cases death when exposed to high amounts of it
This project was one I really enjoyed, I felt like we had a lot of creative freedom to do things how we wanted. I think that overall this was a very successful project, and that I was able to be very creative during this project and kind of branch off and make something totally different instrument wise. I also think that during this project I was able to communicate very well and use that communication to finish all of our work a couple of days early. I feel as though my group and I communicated extremely well since we texted and talked about what parts needed to be done, and that showed in the fact that we got all of our work done early. However there was some room for improvement, I think that I could have been more compassionate towards my group members. I felt as though sometimes I lost my cool and got a bit heated, and I think that it wasn't necessary for the moment. I also believe that during this project I could have been a better problem solver since I asked for the teachers help a lot more than usual, where I probably should have just stuck with it a bit longer. Overall though I think that this project was a success and helped me learn a lot about sound and light waves.
