Summary: My LO describes the real life applications of how we interact with harmonic waves in our daily lives. I describe how guitar stings have certain frequencies and wavlengths which correlate to the various notes that we can hear from a guitar. I chose to format this in a powerpoint to ensure that it is easy to view, as well as being visually appealing. I chose to do a conceptual problem regarding the speed of a wave pulse, which occurs when a guitar string is plucked.
