NEET Physics Waves Velocity Of Sound MCQs

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?

In a resonance tube experiment, the first two resonance lengths are observed at 16 cm and 50 cm. The end correction of the tube is:

The fundamental frequency of a closed air column is 200 Hz. If the speed of sound is 340 m/s, what is the next resonant length of the air column?

A closed air column has a fundamental resonant frequency of 440 Hz. If the next resonant frequency is 1320 Hz, what is the speed of sound in the column?

A sonometer is set on the floor of a lift. When the lift is at rest, the sonometer wire vibrates with fundamental frequency 256 Hz. When the lift goes up with acceleration $a = \frac{{9g}}{{16}}$ vibration of the same wire changes to

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 :

The transverse displacement of string fixed at both ends is given by $y = 0.06\,\sin \left( {\frac{{2\pi x}}{3}} \right)\cos \left( {120\,\pi t} \right)$, where x and y are in metre and t is in second. The length of the string is 1.5m and its mass is $3 imes {10^{ - 2}}\,\,kg$ . The tension in the string is equal to
