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.
First aid guidelines for wounds. 1  For any open wound, your main focus should be to reduce the bleeding and avoid infection by applying pressure on the wound. 2  Next wrap a sterile and absorbent cloth (or a compress) around it.3  To reduce bleeding, you can also raise the injured part above the level of the heart.irst aid guidelines for wounds. 1  For any open wound, your main focus should be to reduce the bleeding and avoid infection by applying pressure on the wound. 2  Next wrap a sterile and absorbent cloth (or a compress) around it.
