The Project
The Project
We were tasked with making instruments that can make different notes using what we learned about wavelength and frequency. I made a chime out of PVC pipes, and my group mates made a slide whistle and a one stringed guitar. We then made a document describing our instruments and listing our different frequencies and notes. Then we presented it and played a song for the class.
Design Process
My team started by first deciding who would build what instrument. Griffin built the string, Kaden built the wind, and I was tasked with building chimes. Next we made a blueprint, and a table listing the predicted wavelengths, frequencies, and notes. Since I was building a chime I used the chime ratio and my material to figure out the pipe lengths and frequencies. Next we headed to the makers space to get to work. We got a couple days to work on the project, but I was done ahead of schedule. My design was simple and easy to build. I made a base out of wood, that would suspend the pipes in the air using string. I drilled holes in the tubes to funnel the string through, but only later I realized that it works better to tie them on, but it was too late. After We were done building, we made a document describing our instruments (thing above), and presented it to the class along with our instruments.
Content
Frequency - The amount of wave cycles that pass by in a second. It is measured in hertz.
Wavelength - The distance from trough to trough or crest to crest on a wave. It is represented by λ. .
Wave Speed - The distance the wave travels over a certain period of time. Measured in meters per second.
Amplitude - The distance from the midpoint of the wave to the top of it.
TRANSVERSE Wave
TRANSVERSE Wave
A wave where the particles of the medium move perpendicular (at right angles) to the direction the wave travels. Think of it like shaking a rope up and down while the wave travels horizontally. Light waves are an example of this.
Longitudinal Wave
Longitudinal Wave
Waves in which the direction of propagation aligns with the direction of vibration of the medium. Sound waves are an example of this.
Electromagnetic Spectrum
Electromagnetic Spectrum
This is the scale in which we measure the EM radiation. It goes from radio waves, that we use every day to send messages and communicate, to gamma rays, that has the smallest wavelength that we know of. Everything before Ultra violet light on the spectrum is know as non-ionizing. Meaning it can't remove electrons from atoms, and hurt you. After that is is ionizngand can't hurt and even kill you.
Reflection
Over the course of this project we all worked very well together and separately to complete our goal. I was good at helping my group mates when they had questions. I felt confident to help them when they needed it. Something I should work on for the next project is motivating my group mates to finish their part. That way we will complete everything and have time to go over it and improve.
