1 - MIT course on Oscilation and Waves by Prof.
Walter Lewin This is a great resource and reference for PHYS 224. Prof. Lewin shows amazing demonstrations and discussions throughout his course. I strongly encourage all the students to watch Prof. Lewin lectures, starting from class 1. http://ocw.mit.edu/OcwWeb/Physics/8-03Fall-2004/VideoLectures/index.htm or http://www.youtube.com/view_play_list?p=854AA255B15C574C 2 - Download Power Point file presented in
class This ppt file shows examples and simulations of oscillations and waves cases discussed in class. 3 - 3D Lissajous figures This is a very nice applet that allows you to visualize Lissajous figures in a 3D simulation of a 2 channels oscilloscope. You can rotate the system and look at the individual signals or at the Lissajous figure itself from different perspectives. http://www.ngsir.netfirms.com/englishhtm/Lissajous.htm 4 - The Sound Spectrograph that
was demonstrated in class This is a software that you can download and install in a PC computer and convert it to a sound spectrograph. You can learn a lot a physics “playing” with a sound spectrograph and musical instruments, crystal glasses, tuning forks, etc. This program will show you a time series of the sound wave with “a single frequency” (e.g. from a single tuning fork, as we demonstrated in class), or the combined wave from the superposition of several frequencies (e.g. several tuning forks simultaneously, your voice, etc.). http://www.sonicspot.com/soundsoftwarespectrograph/soundsoftwarespectrograph.html Other nice sound spectrum tools can be found here: http://www.sonicspot.com/wavetools/wavetools.html Many interesting sound resources can be found at the Homepage of the Sonic Spot: http://www.sonicspot.com/utils.html 5 - Beat Demonstration Applet showing combination of 2 harmonic oscillations with similar frequencies producing beat. http://library.thinkquest.org/19537/java/Beats.html 6 - Forced oscillations with
and without damping Applet showing simulation of forced oscillations with and without damping http://www.walter-fendt.de/ph14e/resonance.htm 7 - Movie of the Movie showing the collapse of
the Movie: You can drag the bar towards the end if you want to see only the resonance and the crash. http://www.archive.org/details/Pa2096Tacoma Picture before the “resonance”: http://memory.loc.gov/pnp/habshaer/wa/wa0400/wa0453/photos/370501pv.jpg Picture after the “resonance”: http://commons.wikimedia.org/wiki/Image:Tacoma_Narrows_Bridge_Falling.png 8 - Simulation of the two pendulums coupled by an ideal spring: http://www.walter-fendt.de/ph14e/cpendula.htm 9 - Simulation the normal modes of oscillation composing 2 pulses traveling with opposite direction in a tensioned string: http://www.calpoly.edu/~gepstein/NormalModes/ 10 - Download Power Point file number 2 -
presented in class This ppt file shows additional examples and simulations discussed in class. 11- Spreadsheet with Fourier Transform
for a triangular profile. |
