List of top Physics Questions on sound asked in MHT CET

Which one of the following statements regarding pitch of sound is 'WRONG' ?
(A) Pitch refers to sharpness of sound.
(B) Tone refers to the single frequency of that wave.
(C) High pitch sound need not be louder.
(D) In general male sound is sharper than that of a female.
Out of the following musical instruments which is ' NOT ' a percussion instrument?
The enclosed air inside a closed box of rigid walls has pressure \(P_1\). The density of air inside this box is constant. On heating the gas, the pressure of the enclosed air is increased from \(P_1\) to \(P_2\). Now it is observed that the sound travels \(1.4\) times faster than at pressure \(P_1\). The ratio \(P_2\) by \(P_1\) is
What is the effect of humidity on sound waves when humidity increases?
Find the ratio of fundamental frequencies \( f_1/f_2 \) for a pipe open at both ends when \( \frac{1}{3} \) of its length is later submerged in water.
Determine the ratio of the speed of sound in Oxygen to that in Hydrogen at the same temperature.
A person standing between two parallel cliffs fires a gun and hears two echoes, first echo after $1$ second and the second echo after $3$ second. The distance between the two cliffs is (Velocity of sound $= 340\text{ m/s}$ )
Three tuning forks A, B and C have respective frequencies \( n_1, n_2 \) and \( n_3 \) related as \( n_1 = 1.03n_2 \) and \( n_3 = 0.99n_2 \). When A and C are sounded together 4 beats are heard per second. The frequencies of fork B and C are respectively
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 ends. What is the length of the organ pipe open at both ends?
The wavelength of sound in any gas depends upon
