What is the length of an open air column that resonates at its first resonant length with a frequency of 560 Hz (speed of sound = 350 m/s)

Respuesta :

Lenght: 0.3125 m

Formulas:

. Wavelenght = 2 * Lenght => Lenght = Wavelenght / 2

&

. Speed = Frequency * Wavelenght => Wavelenght = Speed / Frequency

Data:

. Frequency = 560 Hz

. Speed of sound = 350 m/s

. Wavelenght = ?

. Lenght = ?

Process & Solution:

. Wavelenght = 350 m/s / 560 Hz = 0.625 m

. Lenght = 0.625 / 2 = 0.3125 m
