Standing wave patterns consist of nodes and antinodes. The positions along a medium that appear to be stationary are known as They are points of no displacement. The positions along a medium that are undergoing rapid motion between a maximum positive and maximum negative displacement are known as They are the opposite of the points of no displacement.

The drawing 0.50 m A shows a graph of Amplitude (m) versus Position (m) of two waves traveling to the right at the same speed. 0.25 m x (m) 2.0 4.0 6.0 (a) Using the data in the drawing, determine the wavelength of each wave. Provide your reasoning. -0.25 m- -0.50 m (b) The speed of the waves is 15 m/s. Calculate the frequency of each one.

What are the first three harmonics of a note produced on a 34.7 cm long string if waves on this string have a speed of 276.0 m/s? 1st Harmonic  Hz 2nd Harmonic  Hz 3rd Harmonic  Hz

A water-skier is moving at a speed of 16.7 m/s. When she skis in the same direction as a traveling wave, she springs upward every 6.9 s because of the wave crests. When she skis in the direction opposite to the direction in which the wave moves, she springs upward every 4.2 s in response to the crests. The speed of the skier is greater than the speed of the wave. Determine the speed of the wave in m/s and determine the wavelength of the wave.
