Answer:
Velocity of sound is 512 m/s
Explanation:
for first resonance condition we know that
[tex]\frac{\lambda}{4} = L[/tex]
[tex]\frac{\lambda}{4} = 0.40[/tex]
[tex]\lambda = 1.6 m[/tex]
now the frequency is given as
[tex]f = 320 Hz[/tex]
now to find the velocity of sound we have
[tex]v = \lambda f[/tex]
[tex]v = 1.6 (320)[/tex]
[tex]v = 512 m/s[/tex]
