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]
