Embibe Experts Solutions for Chapter: Sound Waves, Exercise 3: Exercise-3

If we study the vibration of a pipe open at both ends, then which of the following statements is not true?

The number of possible natural oscillations of air column in a pipe closed at one end of length $85 \mathrm{cm}$ whose frequencies lies below $1250 \mathrm{Hz}$ are: (velocity of sound = $340 {\mathrm{ms}}^{-1}$).

The fundamental frequency of a closed organ pipe of length $20 \mathrm{cm}$ is equal to the second overtone of an organ pipe open at both the ends. The length of organ pipe open at both the ends is

$4.0 \mathrm{g}$ of gas occupies $22.4$ litres at NTP. The specific heat capacity of the gas at constant volume is $5.0 \mathrm{J} {\mathrm{K}}^{-1}$. If the speed of sound in this gas at NTP is $952 \mathrm{m} {\mathrm{s}}^{-1}$, then the heat capacity at constant pressure is (Take gas constant $R=8.3 \mathrm{J} {\mathrm{K}}^{-1} {\mathrm{mol}}^{-1}$)

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

Three sound waves of equal amplitudes have frequencies $\left(n-1\right), n, \left(n+1\right)$. They superimpose to give beats. The number of beats produced per second will be :

The two nearest harmonics of a tube closed at one end and open at other end are  $220 \mathrm{Hz} \&\hspace{0.17em}260 \mathrm{Hz}$ What is the fundamental frequency of the system?

A pipe open at both ends has a fundamental frequency $f$ in air. The pipe is dipped vertically in water so that half of it is in water. The fundamental frequency of the air column is now
