Answer:
Length of pipe
meter
Step-by-step explanation:
Speed of a transverse wave on a string
where F is the tension in string and
is the mass per unit length
Thus,
Substituting the given values we get -
Speed of a transverse wave on a string
For third harmonic wave , frequency is equal to
Substituting the given values, we get -
Length of pipe
Substituting the given values we get
for first harmonic wave
Length of pipe
meter
