Sound is a very interesting subject in Physics. Science of sound is melodious provided you understand it. is It is a mechanical wave composed of frequencies within the range of hearing and of a level sufficiently strong to be heard, or the sensation stimulated in organs of hearing by such vibrations.Sound is a sequence of waves of pressure that propagates through compressible media such as air or water. . Here is a most fundamental questions to check your knowledge on sound.
