当温度为20.0摄氏度时,空气柱产生共振。频率
生产的是用计算机记录的;但是,有一个问题,我们无法判断
记录了哪些谐波。我们记录了连续泛音860赫兹,1204赫兹
和1548赫兹。回答下列问题:
a、 基频是多少?
b、 管子是开着的还是关着的?
c、 管子的长度是多少?
英文原题:
An air column is made to resonate when the temperature is 20.0o C. The frequencies
produced are recorded using a computer; however, there is a problem and we cannot tell
which harmonics are being recorded. We record successive overtones of 860 Hz, 1204
Hz, and 1548 Hz. Answer the following questions:
a. What is the fundamental frequency?
b. Is the tube open or closed?
c. What is the length of the tube? 展开
