a column of air in a tube is vibrating at its fundamental frequency of 150Hz. Which of the following frequencies could also exist in the tube as harmonics?
- 75 Hz
- 225 Hz
- 300 Hz
- 450 Hz

Respuesta :

Answer:

-300 Hz

-450 Hz

Explanation:

As we know that frequency of nth harmonic mode is known as

[tex]f_n = \frac{nv}{2L}[/tex]

now we know that for fundamental mode of frequency we will have

n = 1

[tex]f_o = \frac{v}{2L}[/tex]

so we will have

[tex]f_n = n f_o[/tex]

now given that

[tex]f_o = 150 Hz[/tex]

and also we have

n = integer

so we will have

n = 2

[tex]f = 300 Hz[/tex]

n = 3

[tex]f = 450 Hz[/tex]
