List of top Physics Questions on Sound Wave asked in MHT CET

When two tuning forks are sounded together, 6 beats per second are heard. One of the fork is in unison with $0.70 \text{ m}$ length of sonometer wire and another fork is in unison with $0.69 \text{ m}$ length of the same sonometer wire. The frequencies of the two tuning forks are}
In an organ pipe closed at one end; the sum of the frequencies of first three overtones is $3930 \text{ Hz}$. The frequency of the fundamental mode of organ pipe is
The frequency of a tuning fork is $256 \text{ Hz}$. It will not resonate with the tuning fork of frequency}
Two pipes of lengths $\text{L}_1$ and $\text{L}_2$, open at both ends are joined in series. If ' $f_1$ ' and ' $f_2$ ' are the fundamental frequencies of two pipes, then the fundamental frequency of series combination will be (neglect end correction)}
In fundamental mode, the time required for the sound wave to reach up to closed end of a pipe filled with air is '\(t\)' second. The frequency of vibration of air column is (Neglect end correction)
An organ pipe has fundamental frequency $80\text{ Hz}$ . If its one end is closed, the frequencies produced will be (in $\text{Hz}$ ) (Neglect end correction)}

A pipe closed at one end vibrating in fifth overtone is in unison with open pipe vibrating in its fifth overtone. The ratio of \(l_c : l_o\) is [\(l_c = \text{vibrating length of closed pipe}, l_o = \text{vibrating length of open pipe}\)]
Sound waves of frequency $600\ \text{Hz}$ fall normally on a perfectly reflecting wall. The shortest distance from the wall at which all particles will have maximum amplitude of vibration is (speed of sound $=300\ \text{ms}^{-1}$)}
A pipe closed at one end has length $0.8\text{ m}$. At its open end, a $0.5\text{ m}$ long uniform string is vibrating in its 2nd harmonic and it resonates with the fundamental frequency of the pipe. If the tension in the wire is $50\text{ N}$ and the speed of sound is $320\text{ m/s}$, the mass of the string is
What is the ratio of the velocity of sound in hydrogen (\(\gamma = \frac{7}{5}\)) to that in helium (\(\gamma = \frac{5}{3}\)) at the same temperature? (Molecular weight of hydrogen and helium is 2 and 4 respectively.)
A pipe closed at one end vibrating in fifth overtone is in unison with open pipe vibrating in its fifth overtone. The ratio of \(l_c : l_o\) is [\(l_c = \text{vibrating length of closed pipe}, l_o = \text{vibrating length of open pipe}\)]
