The Main Idea
The physical effect of sound as it travels through the medium of water has some unique effects not found in transmission mediums such as air or a solid. Basically, a sound wave consists of a repeating pattern of high and low pressures of energy from the point of the sound’s source as it travels through a medium to a sound receiver. Sound waves, known as rays, behave differently depending on the medium that it travels through: air, water, or a solid. Salt water, as a medium for sound propagation, affects sound by changes in temperature, salinity, and pressure as these sound rays do not propagate in straight lines in the ocean, they are refracted (2). Sound speed refraction results in a bigger angle to the plane of the waves when the speed is increased and a smaller angle when speed is decreased thus these changes cause sound to become dependent in how it propagates from its source to a receiver (3).
