Thesis: Sound waves are able to carry vibrations through a medium which results in the transfer of the energy collected in the vibrations. Transverse waves are vibrations which are at right angles to the wave’s direction of travel whereas longitudinal waves are vibrations along the line of wave’s direction of travel. These waves have a quantifiable speed, wavelength and frequency. Owing to these properties, sound waves have scores of uses. Introduction: Human ear is capable of hearing sounds with frequencies of about 30Hz – 20 kHz. Sound waves are able to travel best through rigid solids rather than through liquids and gases. However, human ears have got accustomed to sound waves passing through air, so are able to hear various things. The loudness of the sound is based on the incoming waves’ amplitude whereas the pitch of the sound is based on the incoming waves’ frequency. Musical instruments work...
