Randall D. Knight — Traveling Waves: Problem 31

A sound source is located somewhere along the x-axis. Experiments show that the same wave front simultaneously reaches listeners at \(x = -7.0 \text{ m}\) and \(x = +3.0 \text{ m}\). a. What is the x-coordinate of the source? b. A third listener is positioned along the positive y-axis. What is her y-coordinate if the same wave front reaches her at the same instant it does the first two listeners?
