List of top Physics Questions on Sound Wave asked in MET

Fundamental frequency of a sonometer wire is \(n\). If the tension is made 3 times and length and diameter are also increased 3 times, what is the new frequency?

A stretched sonometer wire is in unison with a tuning fork. When length of wire is increased by 1%, the number of beats heard per second is 5. Then the frequency of the fork is :

If an observer moves towards a stationary source, then the apparent frequency is given by:

A car travelling on a straight track moves with uniform velocity \(v_1\) for some time and with uniform velocity \(v_2\) for the next equal time. The average velocity of the car is

An open pipe is suddenly closed at one end with the result that the frequency of the third harmonic of the closed pipe is termed to be higher by 100 Hz than the fundamental frequency of the open pipe. The fundamental frequency of the open pipe is

When the wavelength of sound changes from 1 m to 1.01 m, the number of beats heard are 4. The velocity of sound is

5 moles of $SO_{2}$ and 5 moles of $O_{2}$ are allowed to react. At equilibrium, it was found that 60% of $SO_{2}$ is used up. If the partial pressure of the equilibrium mixture is one atmosphere, the partial pressure of $O_{2}$ is

The function of \( Fe(OH)_{3} \) in the contact process is

The velocity of sound in air at STP is 332 m/s. The velocity of sound in air at \( 27^\circ \text{C} \) is:

When a source of sound moves towards a stationary observer, the observed frequency is:
