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.
Open wounds can be classified according to the object that caused the wound. The types of open wound are: 1  Incisions or incised wounds, caused by a clean, sharp-edged object such as a knife, razor, or glass splinter.2  Lacerations, irregular tear-like wounds caused by some blunt trauma.3  Lacerations and incisions may appear linear (regular) or stellate (irregular). contaminated wound, where the wound is as a result of accidental injury where there are pathogenic organisms and foreign bodies in the wound. 2  infected wound, where the wound has pathogenic organisms present and multiplying showing clinical signs of infection, where it looks yellow, oozing pus, having pain and redness.
