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.
Considerations in effectiveness of options for closing a wound are mostly based on a few things. First, the depth of the wound may influence what choice is made. Second, how much scarring results from a wound is a factor important to patients and doctors alike.
