Sound WavesThe absolute technical definition is they move through vibrations created in the atmosphere. It is known to be a mechanical vibration traveling through a given matter as a waveform. Thus, it acclaims an alternative definition as a series of compressional and longitudinal waves moving through air or a given source of medium. Sound waves tend to bounce off a given surface or an object and vibrate against that particular object creating a sound. For instance, if two friends are talking in an enclosed room, their voices bounce off the objects present in that room, like wooden furniture, walls, bed, etc. and thus a sound is created around those objects enhancing a possibility in turn for 'em to listen to one another. If you consider them to travel in space, its existence is a total disapproval. The reason being is pretty obvious. Space is void. Vacuum. An empty space with no matter present at all. Hence, these waves have no particular medium to bounce off against to create a vibration. This is where the question of its existence in such an empty space totally dissolves. This was a short overview on how sound travels through different mediums and materials, like, solids, liquids, gases, plasma, etc. And also how it doesn't travel though vacuum and empty space mediums, is a notable differentiation to consider. Sound exist in a variety of forms. They strictly occur based on vibrations and the vibration of sound waves move in a backward and forward direction. Most of the sound vibrations are pretty obvious and its source of traveling is determined too. Other vibrations are known to be invisible vibrations and are determined by specific scientific experiments. Maximum amount of waves that we are able to listen to travel through air and other solid and liquid materials. It's due to these factors that sound waves are carried from one place to another. On a daily basis, the sound that reaches our ears are transmitted by our surrounding air. It's air that stretches and extends the capacity of the sound vibrations to reach our ears (recipient). When these sound vibrations reach our ears, our eardrums vibrate instantly which in turn sends a message to the brain and stimulates it to react accordingly. These waves traveling through solids and liquids is when they do travel through these mediums they slightly change and sound strange. They cannot travel through a medium of vacuum and empty space as there is no air nor any object to retaliate and react with. Dogs can hear ultrasonic and infrasonic sound waves at a much higher frequency when compared to humans. These waves help animals and insects to detect their danger. The waves act as a warning signal of their possible attacks. The speed of sound is 1,230 kilometers per hour (767 miles per hour). When sound travels through water, sound moves 4 times faster than what it transmits through air. The process of these waves in scientific
