Wave Motion - Pest in the Pool - Assignment Example This natural frequency was calculated to be. Stationary waves commonly referred to as standing waves are waves that appear to be moving back and forth on the same sport i.e. they oscillate instead of making linear motion. This phenomenon can take place if two waves of equal wavelength and frequency travelling in the opposite directions superimpose on each other (Jerry, 2006). On the water, two water waves travelling in the opposite direction can be produced by sending a wave against a barrier that will block further propagation of the wave. Hence reflect the wave back in the opposite way. This reflected wave which is a counter-propagating wave is of the same amplitude, wavelength and frequency as the incident wave. Thus, these two waves will interfere both constructively and destructively (Halliday, Robert & Jearl, 2006). Standing waves being oscillations nature other than linear motion; they take on basic parameters related to oscillations such as; angular frequency and period. The angular frequency, , and period, T, are related according to the formula below; Where  is the velocity of the wave,  is the linear frequency and  is the distance between two successive crests of the incident wave (Feynman, Leighton, and Sands, 2013). The frequency of the propagating wave is the same as the frequency of the wave marker. The frequency can also be obtained from the period of one complete cycle as; Where the crest of one wave and trough of the other wave meets, they cancel out creating a node at that point. Halfway between two nodes the two waves superimpose constructively building an antinode. Antinodes are the points of maximum displacements. The distance between two nodes, L, is related to the wavelength of the wave by; By using a buoyancy board, water waves are generated and sent to the other end of the pool at same interval. The wall of the opposite side of the pool will act as a barrier and reflect the periodic wave back in the opposite

Middle range theories - Coursework Example Having mapped the full extent of the damages the patient had sustained in the accident, it became increasingly imperative that various technology be assembled to aid the patient surmount the challenges she faced with regards to feeding. As thus, a feeding tube was assembled to help achieve this objective. This was through a process medically referred to as gavage (Joanne, 2008). In medical practice, there are many tubes of this kind that, most of them made of polyurethane or silicon. In this case, other nurses and I promptly settled on a nasogastric feeding tube, which is technologically designed to enable feeding of a victim not able to feed normally by inserting the implement through the nose. In this nasogastric intubation exercise, we practically went about passing the feeding tube through the nostril, down the esophagus and into the stomach. The technology proved to be an effective temporary measure to directly help the patient through the challenge. The process is completely delicate and required an outstanding amount of precision with very little margin for era given the vital organs we had to keep watch on and the rather mechanical approach of the intervention. We had to be patient and show a practical depiction of the care required in the nursing profession. The response and commitment the nurses had shown in this procedure was very commendable and was instrumental for the success of the whole process. Having cared for a terminally ill lung cancer patient, I have had first-hand experience to care and stand up for a patient through the intrigues of his final moments of life. In caring for the patient, there were many complex issues involved and equal measure of effort on my side to fully attend to the patient and make him completely at peace and appreciated. To begin with, I implored on the patient to seek spiritual peace upon learning he had a religious personality. Upon research, I was able to give adequate guidance
