Communication (1928)

          According to the film Communication (1928), there are many different assets to the phone back in the 1920's. It starts by introducing the telegraph and how it was used to communicate over seas and onto ships using the morse code as well as the importance of it. Moving on, it showed the way electricity is designed to flow through the phone. With the electricity waves, they also carry sound waves. Electricity is only allowed to flow when the phone is taken off the hook because when sound waves travel through the phone, waves hit carbon granules causing the waves to fluctuate which then activates the electricity to travel. Sound waves travel in multiple directions but is only affected when its direction meets an object that alters it making it travel in a new direction. 
       
      The perfect example to exemplify this idea is the human ear. The sound travels through the Pinna or the outer ear that catches the sound waves and in this case, it was the metal cone designed for the phone representing it. Next, it travels down the middle section of the ear canal (representing the middle section of the phone) and into the tympanic membrane (tympanic membrane representing vibration on the metal plate in phone) where it vibrates sending the sound towards the brain. This is the exact same way that the phone was designed to do when receiving or sending out calls. This is how the telephone has advanced over time.

            This film can be useful to students of modern information and communication because it informs the history on the telephone and their usages. Not only that, but it also talks about the history of it. If someone wanted to know more about the way the telephone processed back then, this would also be the perfect source to provide the information needed. As an audience, we can learn how important it was for the phone to continue communication throughout society and we can also come to understand why the telephone had a large impact on the society. Knowing the importance of the telephone can also be beneficial to our learning experience. Because this was also the stage where technology began to advance, we can also see where and how people developed their ideas into reality.
