Question
Identify the following waves as transverse or longitudinal:
TransverseLongitudinal Compression waves traveling through water.
TransverseLongitudinal The 'wave' mode by fans at a sporting event.
TransverseLongitudinal Sound waves such as music traveling through air.
TransverseLongitudinal A wave train traveling horizontally along a horizontal spring
TransverseLongitudinal A wave traveling along the plucked string of a guitar.
A person lying on an air mattress in the ocean rises and falls through one complete cycle every 5.00 seconds. The crests of the wave causing the motion are 20.3 m apart. Determine the frequency of the wave.
For research purposes a sonic buoy is tethered to the ocean floor and emits an infrasonic pulse of sound. The period of this sound is 74.0 ms. Determine the wavelength of the sound.
Explanation / Answer
the wave travels 20.3m in 5 seconds giving a speed of 4.06m/s
?f = s = 343 m/s (speed of sopund)
? = Wavelength in meters
f = frequency in Hz
? = 343/0.074 = 4635 meters
