Answer:
B) The frequency of the sound is 100 Hz.
Explanation:
Frequency of the sound is always equal to the frequency of the source
So here we know that
length of the string is
L =0.6 m
Speed of the sound is
v = 340 m/s
frequency of the sound
f = 100 Hz
now the wavelength of the sound is given as
[tex]\lambda = \frac{v}{f}[/tex]
[tex]\lambda = \frac{340}{100}[/tex]
[tex]\lambda = 3.40 m[/tex]
