A 0.485-m-long brass pipe open at both ends has a fundamental frequency of 347 Hz. (The coefficient of linear expansion for brass is 19 ✕ 10−6 °C−1.) a) Determine the temperature of the air in the pipe. b) If the temperature is increased by 22.0°C, what is the new fundamental frequency of the pipe? Be sure to include the effects of temperature on both the speed of sound in air and the length of the pipe.
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.
