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.
As nurses, we know that wounds should be measured and recorded precisely. And we know that wounds are tracked by their size in centimeters. Unfortunately, jury members and other non-medical people in the United States are unfamiliar with the metric system. If you tell them a wound is 10 cm long, jury members may picture a wound that is 10 inches long instead of its real length of 4 inches. As a new legal nurse consultant, you can assist attorneys, and eventually juries, by describing wounds in both centimeters and inches.
