Physics of Music Spring 2016 Key terms Bernoullis Equation Pressure vs velocity Compression vs rarefaction Open vs Closed Tubes Node vs antinode Even and Odd harmonics Kundts. Physics 2415 Lecture 28. Michael Fowler, . UVa. Today’s Topics. Waves in two and three dimensions. Interference. Doppler effect. Harmonic String Vibrations. Strings in musical instruments have fixed ends, so pure harmonic (single frequency) vibrations are sine waves with a . Honors Physics. What is a wave. A . WAVE. is a vibration or disturbance in space.. A . MEDIUM. . is the substance that all SOUND WAVES travel through and need to have in order to move. . Two types of Waves. Typically, harmonic motion decreases in amplitude with time….this realistic model describes damped harmonic motion.. The damping effect is a result of friction and internal resistance of the system to further motion.. Physics 2415 Lecture 26. Michael Fowler, . UVa. Today’s Topics. The wave equation. Energy and power of waves. Superposition. Standing waves as sums of traveling waves. Fourier series. Harmonic Waves. Physics 2415 Lecture 27. Michael Fowler, . UVa. Today’s Topics. Standing waves as sums of traveling waves. Boundary conditions. Longitudinal waves: sound. Amplitude and pressure variations. Strings and pipes. CHAPTER 17. Interference. Constructive and Destructive Interference: BEATS. Standing Waves:. Transverse-Stringed Instruments. and . Longitudinal-Wind Instruments.. Diffraction. . Speakers. . 17.6 . Waves transfer energy!. A wave does not carry matter . It only moves matter as it travels through it.. Waves. Compression (longitudinal) waves . are waves in which the particles of the medium move in a direction . 1-d and 2-d waves. Wavefront. :. The actual 2-d wave . that we see moving. Ray:. The “vector”, drawn perpendicular to the . wavefront. , that shows the direction in which the wave is propagating (. for . two identical waves traveling in opposite directions.. .  Snapshots . of the blue and the green waves and their red sum shows a wave that appears to not be traveling..  Because . the resultant red wave is not traveling it is called a . Before the waves are made the particles are same distance apart. While waves moves through the medium the particles . compress. together, then they spread further apart (stretched areas)- . rarefaction.. A wave is any disturbance that transmits energy through matter or empty space.. Energy can be carried away from it’s source by a wave. As a wave travels, it does work on everything in it’s path. Warm-Up: February 17/18, 2016. Vibrations and Waves. Chapter 14. A . periodic motion . repeats in a regular cycle.. Examples include:. Pendulums (such as on a grandfather clock). A mass at the end of a spring. Michael Fowler, . UVa. Today’s Topics. The wave equation. Energy and power of waves. Superposition. Standing waves as sums of traveling waves. Fourier series. Harmonic Waves. A simple harmonic wave has sinusoidal form:. water. waves.... 4/5/2019. Physics 214 Fall 2010. 2. 1S-13 Slinky on Stand. Creating longitudinal compression waves in a slinky. What happens when you pull back and release one end of the slinky . ? .
