An 80.00 cm guitar string has a mass of 3.25g. It has been tuned so that its fundamental mode of oscillation has a frequency of 256 Hz. A) What wave speed is required on the string? B) What string tension is required? C) What is the wavelength of the sound waves produced in the surrounding air at 20 degrees Celcius? D) Assume the string is isotropically emitting a total acoustic power of 8.5 mW, determine the sound level 22m away? (assume a point source)
Interference of sound
Seiche
A seiche is an oscillating standing wave in a body of water. The term seiche pronounced saysh) can be understood by the sloshing of water back and forth in a swimming pool. The same phenomenon happens on a much larger scale in vast bodies of water including bays and lakes. A seizure can happen in any enclosed or semi-enclosed body of water.
