Transcript of Waves: Medical and Industrial Applications

Medical and Industrial
Applications What are waves? Waves are a complicated form of transporting energy. Transverse wave: Longitudinal wave: Waves play an
important role in
many everyday
processes Such as... Water waves produce electricity, which provides the electrical power used to run everyday appliances such as the lights in your house, your refrigerator, and television. Cons are that the metal is hard to maintain, because it can rust quickly from exposure to the water. In industrial manufacturing plants as well as medical procedures, ultrasonic waves are used to cut things. The ultrasonic waves are really small but it has high frequency, which can be used as a sort of "knife" without having to exert pressure on the object at hand. Doctors use ultrasonic scalpels during surgery, and ultrasonic industrial knives are used to cut hard-to-cut materials. A possible con is that these tools require a high skill level to use them without danger. An industrial ultrasonic knife: An ultrasonic scalpel: Ultrasonic waves are also used to weld metals together without solder and flux, by vibrations. While this does make welding easier, it is easy to destroy the metals in unskilled hands. One application of shock waves in medicine is to disintegrate kidney stones. They are also used in orthopedics and traumatology to treat disease of the tendons. It helps patients rebuild muscle and strength. One con is that this method isn't always effective. Shock waves disintegrating

A con is that MRI's can't detect every issue. MRI Ultraviolet light at relatively short wavelengths are used for Ultraviolet germicidal irradiation (UVGI) in the medical industry. Also, UVGI is used to sterilize goggles in school chemistry labs. One con is that UVGI can't get rid of all germs. The oil industry uses electromagnetic waves in order to highlight oil deposits thousands of feet below the ocean floor. This subsea mapping process has allowed the search for oil to become much easier, and less costly. However, undersea structures can sometimes be so thick that it blocks the waves. An example of an undersea oil map Manufacturing plants use heaters that utilize infrared waves to distribute heat across the factory. These heaters have been the most modern, and cost-effective way to heat large rooms. However, several of these heaters are required to heat very large rooms.
