WAVES: BLOG 12

While we were learning about standing waves, I kept envisioning this scene from the move Miss Congeniality. In this scene, Gracie is playing a glass harp as her talent, and I learned that the glass harp works due to physics. In the glasses, standing waves are produced as the air inside vibrates at one (or more) of the glasses resonant frequencies. The amount of water inside each glass changes the pitch each glass makes, which is why she drank some of the water out of the glass that was out of tune. I found it interesting how we were learning about something that shows up in one of my favorite movies.
