Solutions Applets and Animations Traveling Waves Illustrating the sign of the time term for traveling waves moving from left to right or right to left. Transverse Wave The Transverse Wave model displays the motion of a transverse wave on a string.

The simulation allows an arbitrarily polarized wave to be created. The Wave Representations model displays two representations of a sinusoidal wave on a string. One shows a movie of the wave traveling along a string - you can think of this representation as a sequence of photographs. The second representation is a plot of the displacement as a function of time for two points on the string you can select which two points to use.

The Wave Function Plotter model displays a one-dimensional wave function u x,t depicting a disturbance at position x and time t. The disturbance can be mass density, pressure, or electric field depending on the physical context.

The default wave function is sinusoidal but any other analytic function can be entered in the text box. This simulation lets you see sound waves.

Adjust the frequency, volume, and harmonic content and you can see and hear how the wave changes. Move the listener around and hear what she hears. The Doppler Effect model displays the detection of sound waves from a moving source and the change in frequency of the detected wave via the Doppler effect.

In addition to the wave fronts from the source a graph depicting the time of emission and time of detection of each of the wave fronts is given. This applets shows the waves generated by a moving source.

They observe that a pendulum makes exactly 10 complete back and forth cycles of motion in Determine the period of the pendulum.

Strong winds can apply a significant enough force to tall skyscrapers to set them into a back-and-forth motion. The amplitudes of these motions are greater at the higher floors and barely observable for the lower floors. It is said that one can even observe the vibrational motion of the Sears Tower in Chicago on a windy day. As the Sears Tower vibrates back and forth, it makes about 8. Determine the frequency and the period of vibration of the Sears Tower. The spin rate of a CD-ROM varies according to the location on the disc from where data is being accessed.

When accessing data from the inner circles of the disc, the CD can spin at a rate as high as revolutions per minute. Determine the frequency in Hertz and the period in seconds of the spinning CD.

Like all planets, the planet Venus orbits the Sun in periodic motion and simultaneously spins about its axis. Just as on Earth, the time to make one complete orbit i. And the time to make one complete revolution about its axis i.

The period of orbit for the Earth is But when these same values for Venus are expressed relative to Earth, it is found that Venus has a period of orbit of days and a period of rotation of days. So for Venus inhabitants, a day would last longer than a year!

Determine the frequency of orbit and the frequency of rotation in Hertz on Venus.
