Question 1
What is the form of the one-dimensional wave equation?
- \\( \\frac{\\partial^2 u}{\\partial t^2} = c^2 \\frac{\\partial^2 u}{\\partial x^2} \\)
- \\( u = f(x+t) + g(x-t) \\)
- \\( u = c(x-t) \\)
💡 Hint: Look for the equation that involves second derivatives.

Challenge Problems
Push your limits with challenges.
Question 1
Given the wave equation \( \frac{\partial^2 u}{\partial t^2} = 9 \frac{\partial^2 u}{\partial x^2} \) and the initial conditions \( u(x, 0) = e^{-x^2} \), \; \frac{\partial u}{\partial t}(x, 0) = 0 \), derive D'Alembert's solution and find \( u(x,t) \).
💡 Hint: How does the Gaussian shape of the initial condition influence the wave function?
Question 2
Create your own initial conditions based on real-life wave situations, derive the respective D'Alembert's form, and discuss the implications of your findings.
💡 Hint: Variation in initial conditions will significantly alter wave behavior.
