Description:  The following 3 video clips show plane waves produced at various frequencies.  The meterstick is again included for measurements and the video is shown at a rate of 30 frames/sec.

Measurements for this clip:

1.  Using a stationary object in the video, determine the frequency of the waves in Hertz (waves/sec).

2.  Determine the wavelength of the waves.

Measure a different frequency.
