Standing wave on 2D surface
Standing wave on 2D surface
Courtesy Oleg_AlexandrovThe mixture of corn starch and water literally stands up in the video below because of standing waves. If you want to try this, place a mixture of corn starch and water on cookie sheet. Hold the cookie sheet down over a bass speaker with some of your fingers. The speaker should be playing music with low frequencies. By varying the distance an position of your fingers you can alter the standing wave patterns within the cookie sheet.
