Sound Wave
The science of sound waves entails the study of the related features such as the speed and intensity. Some sounds are louder than others, according to the intensity of the vibrating air molecules and frequency of the sound waves (Ward, Bermingham & Wherry, 2000). The traveling of the sound waves is affected by a number of factors. For example, weather conditions such as temperature and pressure affect the behavior of sound waves in terms of speed and intensity (Ward, Bermingham & Wherry, 2000). The intensity of sound may also be a combination of different pitches, which are interpreted in various ways by the human brain through the ear drum. This paper seeks to answer the question as to what eventually happens to a sound wave traveling through the air.
The sound wave constitutes of a number of vibrations which result from molecular collisions in the air space (Ward, Bermingham & Wherry, 2000). The rate of the vibrations determines the pitch of the sound. When the vibrations are intense, the pitch of the sound is high, and the opposite is true. The law of kinetics states that energy is neither created nor destroyed but can be changed from one state to another.
As energy in the form of sound travels through a medium such as air, it pushes the air molecules thus causing friction between them. Sound waves thus lose energy due to the increased friction between the molecules. The friction also decreases the intensity of the sound waves (Ward, Bermingham & Wherry, 2000). As this happens, other forms of objects in the environment such as humans absorb the energy in the sound wave until the time when t...
