The aim of wound bed preparation is to create an optimal wound-healing environment by producing a well vascularised, stable wound bed with minimal exudate. Bacterial load has a direct impact on wound healing. The management of the bacterial load by either local or systemic therapy is important in wound management.
Refraction of Sound Waves. Refraction of waves involves a change in the direction of waves as they pass from one medium to another. Refraction, or bending of the path of the waves, is accompanied by a change in speed and wavelength of the waves. So if the media (or its properties) are changed, the speed of the wave is changed.
Intensity of the fringes decreases as we move along either side of the central maxima. Refraction. When a wave passes from one medium to another at any angle except 90Â° and 0Â°, its line of travel changes at the interface due to the change in velocity of the wave. This is what we call refraction.Although light waves provide most of the examples for refraction, any other wave can also refract.ntensity of the fringes decreases as we move along either side of the central maxima.
