sat2物理 封闭管的问题
Barron的这句话是啥意思 one way to describe a vibrating air column is to say that it has natural frequencies of vibration.Its lowest frequency of vibration is one for which the wavelength equals approximately four times the length of the air column.
The overtones that a closed air column can produce are odd multiples of the fundamental frequency.这里的fundamental frequency

Answer 1

one way to describe a vibrating air column is to say that it has natural frequencies of vibration.Its lowest frequency of vibration is one for which the wavelength equals approximately four times the length of the air column
一个方法来描述振动空气柱是说它的固有振动频率.其最低振动频率之一,波长约等于四倍的空气柱的长度
The overtones that a closed air column can produce are odd multiples of the fundamental frequency
言外之意,一个封闭的空气柱是能产生奇数倍数的基本频率
