1. The problem statement, all variables and given/known data Our teacher asked us to find a useful use of the wave equation, in which we must explain how the wave equation is used in the application we chose, in which will be a 2 minutes at max speech. 2. Relevant equations Wave equation v=f*λ 3. The attempt at a solution I have been looking around the internet but have had little luck, the uses I have found are either not useful or exciting, in which the teacher wants, or in too much detail. So I was wondering if any of you can give me some interesting uses of the wave equation.
