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.
1 The doctor should tell you how long this should be. 2  It is usually 1-3 days depending on the type of stitches and the size of the wound. 3  Once you can get them wet, gently wash the wound over the stitches or staples with soap and water when you shower.4  Do not submerge the wound underwater, like in a bath or when swimming.
