A sound wave travels through a medium with a bulk modulus $B$ and density $\rho$. If the medium is suddenly compressed such that its density becomes $1.5\rho$ while the temperature remains constant, what is the new speed of sound in the medium?

Intensity level of sound of intensity $I$ is $30\,\,dB$. The ratio $\frac{I}{{{I_0}}}$ is (Where ${I_0}$ is the threshold of hearing)

Transverse waves can propagate in

An earthquake generates both transverse $\left( S \right)$ and longitudinal $\left( P \right)$ sound waves in the earth. The speed of $S$ waves is about $4.5\,\,km/s$ and that of $P$ waves is about $8.0\,\,km/s$. A seismograph records $P$ and $S$ waves from an earthquake. The first $P$ wave arrives $4.0{\rm{ }}min$ before the first $S$ wave. The epicenter of the earthquake is located at a distance about

In Melde’s experiment, three loops are formed by putting a weight of $8\,\,g$ in a massless pan. The weight required to form two loop is

Under identical conditions of pressure and density, the speed of sound is highest in a

The frequency of the fundamental note in a wire stretched under tension $T$ is $v$. if the tension is increased to $25 T$, then the frequency of the fundamental note will be

A car moving with a velocity of $36{\mkern 1mu} \,\,{\mkern 1mu} k{m^{ - 1}}$ crosses a siren of frequency $500\,\,Hz$. The apparent frequency of siren after passing it will be

5 beats/second are heard when a turning fork is sounded with a sonometer wire under tension, when the length of the sonometer wire is either 0.95 m or 1 m. The frequency of the fork will be :

Two monochromatic coherent light beams A and B have intensities $I$ and $\frac{I}{4}$ respectively. If these waves are superposed, the maximum and minimum intensities will be

Two identical plain wires have a fundamental frequency of $600$ cycle per second when kept under the same tension. What fractional increase in the tension of one wires will lead to the occurrence of $6$ beats per second when both wires vibrate simultaneously
