On a guitar, the strings played vibrate between two fixed points. The frequency of vibration is modified by changing the string length using a finger. The different strings have different wave speeds. When a string is plucked, a standing wave forms between the bridge and the finger. bridge- finger 62 cm 1a. Outline how a standing wave is produced on the string.

A highway overpass was observed to resonate as one full loop (A) when a small earth- quake shook the ground vertically at 3.0 Hz. The highway department put a support at the center of the overpass, anchoring it to the ground as shown below. What resonant frequency would you no expect for the overpass? It is noted that earthquakes rarely do significant shaking above 5 or 6 Hz. Did the modifications do any good? Explain. Copyright ©2006 Pearson Education, Inc.

The wavelength is a fundamental property of a mechanical wave. Which of the following is true about the wavelength of a mechanical wave? It can be divided by a frequency to determine speed. It is the distance from crest to trough. It measures the distance that the medium has travelled. It is the distance over which a vibration repeats itself.
