Sound occurs when a vibration travels through the molecules of a medium, such as air. Sound vibrations travel as waves of high and low pressure, which are known as compression waves. Sound can travel through other mediums as well, such as solids and liquids....
Relatively high velocities (4+ km/s) occur at shallow depth in the midslope region and may indicate imbricate slices of indurated sediment within the slope. From the combination of the reflection and refraction data and previous refraction work we infer the presence of at least two separate ...
In fact, the index of refraction is a random variable in actual seawater medium. To describe its random characteristics, the mean square of the index of refraction is first introduced as (2.151)μ2¯=(Δcc0)2¯ where c0 is the mean sound velocity, and (Δc)2¯ is the mean ...
The change in direction of a beam when it crosses a boundary between two media in which the speeds of sound are different is called refraction (Fig. 3.2). If the angle of incidence is 90 degrees, there is no beam bending, but at all other angles there is a change in direction. Refra...
Reflection and refraction of waves occur at the interface between two different media. These two fundamental interfacial wave phenomena form the basis of fabricating various wave components, such as optical lenses. Classical refraction—now referred to as positive refraction—causes the transmitted wave ...
