Experiment 112-5 Thin Film Interference Introduction When two waves of equal intensity combine‚ the intensity of the resulting wave can be anywhere between zero and four times the intensity of the individual waves‚ depending upon the phase difference between them. When they are in phase (the maxima coincide with maxima and the minima coincide with minima)‚ maximum intensity results. When they are exactly out of phase (the maxima of one wave coincide with the minima of the other wave)‚ the

Wayne Bertram Williams: Atlanta Child Killer Police circulated this photo at the time showing victims of the Atlanta killings. Photo from CNN Forensic Fiber Analysis Case Study The best-known‚ if not the best-reasoned fiber case in American legal history involving fiber evidence issues is the Wayne Williams trial growing out of the famous Atlanta murders of twelve African-American males in 1979-1980. The Williams case involved all of the subjects still in controversy as we

1. The physical science unit applies principles and techniques of chemistry‚ physics‚ and geology to the identification and comparison of crime scene evidence. 2. The wide variation in which services are offered in different crime laboratories is due to variations in local laws and budgetary and staffing limitations only. 3. The tendency of the public to believe that every crime scene will yield forensic science evidence and their unrealistic expectations that a prosecutor’s case should always

Over the centuries equine have been prone to many injuries and diseases. Most of these injuries generate from overworking the animal or simply a lack or care. Many common injuries such as bone fractures or ligament injuries require intensive care as well as a substantial amount of time for recovery. Sports horses by very nature have a higher percentage to encounter such injuries. These injuries can become a huge problem not only physically‚ but can also determine the lifespan of the injured horse
