Hello, I'm MusikAnimal. I wanted to let you know that I reverted one of your recent contributions —the one you made with this edit to Longitudinal wave— because it didn’t appear constructive to me. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. &mdash; MusikAnimal  talk  16:15, 13 March 2015 (UTC)
