ANALYSIS

Longitudinal waves that travel into something like an elastic medium, they are called

sounds waves. It is likewise characterized as the example of unsettling inuence brought

about by the development of vitality going through a medium, for example, air, water, or

whatever other uid or strong matter as it spreads far from the source of the sound.

Longitudinal waves are compressional waves which go through the air through a

progression of rarefactions compressions. In directing this experiment, our gathering has

experienced a few issues and troubles after doing the experiment. One of the troubles

our gathering has experienced is the person who is rubbing the rod isnt legitimately

stroking the pole. !nother troublesomely that our gathering has experienced is the

determination of the length of the dust. "hat we did in this trial was we created

longitudinal waves through rubbing the rod with the utilization of a cloth with rosin. "e

experienced issues in delivering the waves in light of the fact that on the o# chance that

we simply rub the pole delicately the wavelength of the waves framed is to short and in

the event that we attempt to rub it truly hard the glass tube shakes now and again

exasperating lycopodium powder and the waves shaped. $hrough practice we could

minimize mistakes. $he temperature of the room is additionally huge since it inuences

the speed of sound in air, wherein as the temperature rises the speed of sound in air

increments.

CONCLUSION

  Our destinations in this examination were accomplish by our group which

were, to decide the velocity of the sound in a metal rod and, to decide the speed of

sound in the tube applying the standards of resonance. $he hypothesis is that the sound

in solid can be controlled by applying the rule of resonance. In this trial, when the meta

rod was vibrated, it created longitudinal waves like reverberating air segment in a tube

open at both %nishes. &y utilizing the resonances principle, we could register the speed

of sound in a metal rod by comparing the fre'uencies of the metal rod and air. $he

%gured speed of sound in metal bar was ()*+.) m-s, which is generally near the

estimation of the (*/.0) m-s from the e'uation ). "e accomplish trying so as to

everything on the targets a few endeavors on the rod and assembled numerous

information as we can with the given time given to us. &y the stroke connected to the

rod, it produces friction and additionally longitudinal waves on the tube from the role at

e'uivalent recurrence that outcome with having a high pitch sound. $he speed of sound

was known on account of the noticeable wave design made of lycopodium powder.
