This semester I took Elementary Physics because it was a pre-req that I needed. To be honest, I had no clue or the slightest idea what physics consists of. (silly, I know) I feel after taking this course, I have more of an idea how physics is in our everyday life and actually question and wonder how things exactly work. It definitely opened up my mind more to things, and started thinking about how things work and why.
For my group project our topic was waves and vibrations. Although when I think of sound I had never thought of how the sound is being produced or in fact that it is waves that can proudce sound. While researching, I also learned more about how physics relates to medical diagnostic sonography. It was fascinating to learn how phsyics relates to ultrasound. There are frequencies used in ultrasound diagnosis. Ultrasound relies on high frequency sounds to image the body and diagnose patients. Ultrasounds are therefore longitudinal waves which cause particles to oscillate back and forth and produce a series of compressions and rarefactions. Ultrasound is produced and detected using an ultrasound transducer. Ultrasound transducers are capable of sending and ultrasound and then the same utransducer can detect the sound and convert it to an electrical signal to be diagnosed.
After taking this course, I realized physics is in everything, from microwaving our food to just standing in a room, taking photos. I never wondered why, well I have about when microwaving food how come only certain spots are hot and certain spots are cold, I just figured it needed to be heated up longer not that because certain waves through the microwave didnt warm it up or to sit the food on the edge of the turn table. This course was a great intro into physics.
