WebSolution: The number of vibrations per second or frequency determines the pitch of a sound. Frequency is directly proportional to pitch. Higher the frequency, higher the pitch. WebSound energy is the energy that we create when sound waves move outward from a vibrating article or sound source. Furthermore, these waves are wellsprings of weight that travel through the air, water, or different materials like metal or wood. This kind of vitality is really a mechanical vitality source.

WebSound is a longitudinal wave, which means that the vibration of the air is in the direction of travel of the sound wave. Sound is invisible, so we have to animate to see it. (For film clips of visible examples, see Travelling Waves ). In the animation below, the top graph shows a sine wave y (x'), where x' is a coordinate moving with the wave. WebSound is all about vibration. To make a sound, something has to vibrate — whether that’s the string of a guitar, the larynx (voice box) of a person, or the loudspeakers of your radio. how long after breast development is menarche
