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.
The vibrations are transferred to another medium, usually the air, and travel through it as sound waves. You hear a sound when its vibrations reach your eardrum, causing it to vibrate. The pitch of a sound is directly related to the frequency of the vibrations of its waves.he vibrations are transferred to another medium, usually the air, and travel through it as sound waves.
