At a special angle known as Brewster's angle, no p-polarized light is reflected from the surface, thus all reflected light must be s-polarized, with an electric field perpendicular to the plane of incidence. A simple linear polarizer can be made by tilting a stack of glass plates at Brewster's angle to the beam.
In this particular instance, we would start off by measuring the wound in the length dimension. Where there is the maximum length of this wound of approximately 5.7 centimeters. The width would then be measured at its maximum point of width which is 2.5 centimeters. The depth we then would determine by probing the wound with our cotton-tipped applicator using the cotton end.
- generally puncture wounds do not cause serious external bleeding but there may be significant internal bleeding and damage to vital organs. 4. Incision â an open wound with clean, straight edges usually done with a sharp instrument. 5. Avulsion â involves tearing off or loss of a flap of skin. collection of blood under the skin and tissue. B. Open Wounds â are injuries with break in the skin or mucous membrane 1. Abrasion â superficial loss of skin resulting from rubbing or scraping the skin over a rough or uneven surface 2. Laceration â tear in the skin that can be partial or full thickness cut.
