Question

Pick out the correct statement in the following with reference to stationary wave pattern

• A. In a tube closed at one end, all the harmonics are present
• B. In a tube open at one end, only even harmonics are present
• C. The distance between successive nodes is equal to the wavelength
• D. In a stretched string, the first overtone is the same as the second harmonic

Answer 1

Answer: (D)

In a stretched string, the first overtone is the same as the second harmonic

Answer 2

$f_{2}=2\,f_{1}=$ First overtone or second harmonic

$n=2$
Second harmonic first overtone
where $f_{1}=$ fundamental tone or first harmonic.
In a stretched string, the first overtone is the same as the second harmonic.
