Given the wave equation \( \frac{\partial^2 u}{\partial t^2} = 9 \frac{\partial^2 u}{\partial x^2} \), apply D'Alambert’s solution with \(u(x, 0) = x^2\) and \(\frac{\partial u}{\partial t}(x, 0) = 0\).
💡 Hint: Start by identifying your basic displacement function and observe how it interacts through D'Alembert's framework.
Evaluate the physical implications of using D'Alembert's solution in modeling sound waves in air compared to sound waves in water. Discuss how different properties of the media affect the waves.
