(B) For a closed organ pipe of length $l$,the fundamental frequency (first note) is given by $n_1 = \frac{v}{4l}$.Given $v = 330 \ m/s$ and $l = 1 \ m$,we have $n_1 = \frac{330}{4 \times 1} = \frac{330}{4} \ Hz$.The frequencies of the notes in a closed pipe are given by odd harmonics: $n_k = (2k - 1)n_1$,where $k = 1, 2, 3, ...$.The first note is $n_1 = 1 \times n_1$.The second note (first overtone) is $n_2 = 3 \times n_1 = 3 \times \frac{330}{4} \ Hz$.

Longitudinal Stationary Waves (Organ Pipes) and Resonance Tube

The second overtone of an open organ pipe has the same frequency as the first overtone of a closed organ pipe $L$ metre long. The length of the open pipe will be:

View Solution

$A$ tuning fork of frequency $340 \, Hz$ is sounded above an organ pipe of length $120 \, cm$. Water is now slowly poured in it. The minimum height of water column required for resonance is .... $cm$ (speed of sound in air $= 340 \, m/s$)

Medium

View Solution

Two open organ pipes give $4$ beats/sec when sounded together in their fundamental modes. If the lengths of the pipes are $100 \ cm$ and $102.5 \ cm$ respectively,then the velocity of sound is ..... $m/s$.
