mind, I dove in with the desire to apply a different perspective of music. Diagram 1 One of the earliest discoveries of how string function comes from the Greek philosopher, Pythagoras. The wavelength and pinches between strings are what differentiate the varying notes. As shown in Diagram 1, the wavelengths have specific spacing in between, which are directly related to mathematics. Nodes, or pinches, are strategically and mathematically placed to resonate precise pitches, and particular ratios

Formative assessment: Early in the investigation, and as the students collect their data, the skills objective will be assessed through visual inspection. The second data table should show the following patterns as the harmonics range from 1 to 5: the wavelength decreases, the frequency increases, and the velocity remains the same. Any patterns that deviate from this will indicated errors in data collection which will be addressed to produce precise data. At this point, the students will have enough time

Introduction In this project, I am going to investigate the question ‘are cell phones dangerous’. I will show how a cell-phone works and how radiation caused by cell-phones may affect you, I will show you different viewpoints from different sources and go through identifying key points and evaluate their arguments I will then give you my own opinion based on the facts and research I have conducted. What is the electromagnetic spectrum? The electromagnetic spectrum is a range of different Electromagnetic

To our eyes, sunsets often appear reddish in color in their final stages which is all based on wavelengths; “As the sun drops towards the horizon, it progressively loses violets and blues, then greens and yellows, and finally even the oranges, leaving only the reds behind” (Ethan, 2013). High frequency waves, or the GBIV of ROYGBIV, are scattered more

gives significant benefits. Radiation also can be innately occurring or man made. Most sorts of radiation in commercial use are electromagnetic; those occur of the structure regarding waves up to expectation vary only by means of their wavelengths. When the wavelengths are a too small also short to be seen they

Introduction The purpose of this experiment was to test the effects that different sound barrier materials (foam, fiberglass, and cork) had on sound absorption at varying frequency levels. It was hypothesized that foam would be able to absorb the most sound for all frequency levels. Sound is the mechanical disturbance from a state of equilibrium that propagates though an elastic material medium, which was air in this project. (1) Air is considered an elastic medium because it tends to return to

spectroscope is able to display the emitted light by presenting the bright interference patterns of the diverse wavelengths which make up the spectrum. By looking through the eyepiece, a spectrum will appear on either side of the slit – the slit starts all of the light waves passing down the tube “in phase” so that they arrive at the slits in the diffraction grating at the same time. When wavelengths are in phase, they create constructive interference, which results in double the amplification, while wave

Visiting Artist Series - Michael Snow, "Wavelength" The 1960s was a turning point for American experimental cinema, as the contemporaries of this time began to play with elements that allowed the artist to express his or her own individual perception. Many techniques that are synonymous with avant-garde film today were developed during this period. Artists such as Bruce Conner began to experiment with found footage, while Stan Brakhage created abstract rejections of pop culture. An important milestone

was shot through the sample to detect the contaminant. The first ever spectrophotometer was only developed to calculate pH levels and never used wavelength to calculate the abundance of chemicals within a sample. After many years of developing the spectrophotometer, a glass prism was installed. This allowed the spectrophotometer to use light wavelength to calculate the concentration of chemicals within a sample. The light was able to read the preferred contaminant because a reagent attached to
