  • Ceperley, Peter (2007-12-04)
    This animation shows the time dependence of the complex phasor representation of a one dimensional traveling wave. The wave is seen as a rotating helix.
  • Ceperley, Peter (2007-12-04)
    This animation shows the time dependence of the cosine representation of a traveling wave.
  • Ceperley, Peter (2007-12-08)
    This animation shows the temporal behavior of an elemental rotor as is basic to the use and understanding of phasors. Phasors are heavily used in physics and electrical engineering to mathematically work with oscillations ...
  • Ceperley, Peter (2007-12-08)
    This animation demonstrates the addition of two phasors rotating at different rates to produce a beating sinusoidal signal. To connect the process to real life, two bungy jumpers to provide the oscillating waveforms.
  • Ceperley, Peter (2007-12-08)
    This animation demonstrates the addition in time of two sinusoid signals added together by means of phasors. To make the concept connected to real objects, two bungy jumpers are used to connect the phasors with real ...
  • Ceperley, Peter (2007-12-19)
    Animation of a simple one dimensional traveling wave. This animation shows a monkey creating traveling waves on a string.
  • Ceperley, Peter (2007-12-19)
    Animation of a two dimensional wave propagating through a mesh. The wave is aligned with one of the axes.
