Visualizing Sound

The most interesting part of the video in my opinion was how they were able to visualize the sound on video. What they did to show movement in the air was using a candle to bend the light rays coming from a light bulb. That light then doesn't reach the focal point of the camera, making the subject dark and showing movement in the air. By being able to see sound visually, its helped me understand how fast it actually travels and the formation of the sound waves. Mathematically I know that the speed of sound is 343 meters per second, but being able to see the actual waves move through the air helps me understand it better. Also by seeing the wave, I'm able to see its proper circle shape. Normally, I think of a wave like a sine wave, but thats not how they actually look. By seeing sound visually, I'm able to understand its basic characteristics even better.
