Waves and Sound questions with solutions

Two wires made of the same material, one thick and the other thin, are connected to form a composite wire. The composite wire is subjected to some tension. A wave travelling along

Two identical loudspeakers, placed close to each other inside a room, are supplied with the same sinusoidal voltage. One can imagine a pattern around the loudspeakers with areas

The frequency of the sound produced by a siren increases from 400 Hz to 1200 Hz while its amplitude remains the same. Therefore, the ratio of the intensity of the 1200 Hz wave to

Two factories are sounding their sirens at 400 Hz each. A man walks from one factory towards the other at a speed of 2 ~m / s . the speed of sound is 320 ~m / s . The number of

A vibrator of frequency f is placed near one end of a long cylindrical tube. The tube is fitted with a movable piston at the other end. An observer listens to the sound through a

A whistle whose air column is open at both ends has a fundamental frequency 500 Hz . The whistle is dipped in water such that half of it remains out of water. What will be the

A man stands at rest in front of a large wall. A sound source of frequency 400 Hz is placed between him and the wall. The source is now moved towards the wall at a speed of 1 ~m /

In a stationary wave

An empty earthen pitcher is kept under a water tap and starts filling with water as the tap is opened. The pitch of the sound produced

A student while performing experiment with a sonometer with bridges separated by a distance of 80 cm , missed out some of the observations. However, he claimed that the three

The combination of a steel wire (length 80 cm , area of cross section 1 ~mm^2 ) and an aluminium wire (length 60 cm , area of cross section 3 ~mm^2 ) joined end to end is

Two wires, made of same material, one thick and the other thin are joined to form one composite wire. The composite wire is subjected to the same tension throughout. A wave

Two factories are sounding their sirens at 400 Hz each. A man walks from one factory towards the other at a speed of 2 ~m / s . The velocity of sound is 320 ~m / s . The number of

In many situations the point source emitting a wave starts moving, through the medium, with velocity V greater than the wave velocity in that medium. In such a case when source

A sound source of constant frequency travels with a constant velocity past an observer. When it crosses the observer the sound frequency sensed by the observer changes from 449 Hz

The frequency of the third overtone of a closed end organ pipe equals the frequency of the fifth harmonic of an open end organ pipe. Ignoring end correction, the ratio of their

The intensity of sound at a point P is I_0 , when the sounds reach this point directly and in same phase from two identical sources S_1 and S_2 . The power of S_1 is now reduced

A sound source of fix frequency is in unison with an open end organ pipe of length 30.0 cm and a close end organ pipe of length 23.0 cm (both of same diameter). Both pipes are

A rope of mass m and length L is suspended vertically. A mas M is suspended from bottom of the rope. A transverse wave is produced on the rope, which travels the length of rope in

When the speaker S_1 is switched O N , the sound intensity at a point P in a room is 80 dB . But when the speaker S_2 is switched ON ( S_1 is switched OFF), the sound intensity at

A rope of mass M and length L hangs vertically. Time needed for a transverse pulse to travel from its bottom end to the support is

A police car, moving at speed of 108 ~km / hour, approaches a truck moving at 72 ~km / hour in opposite direction. The natural frequency of the siren of the car is 800 Hz and the

An open-end organ pipe 30 cm in length and a closed-end organ pipe 23 cm in length, both of equal diameter, are each sounding their first overtone and both are in unison at 1100

Which of the following functions does not represent a traveling wave

Two plane progressive waves travelling on a string as aligned & y_1=2.5 × 10^ -3 (30 x-420 t) & y_2=2.5 × 10^ -3 (30 x+420 t) aligned superimpose to produce a standing wave. The
