Challenge Problems
Push your limits with challenges.
Question 1
A drum skin vibrates when struck. Using D'Alembert's solution, model the sound wave emitted from the drumhead assuming an initial shape: $$f(x) = \sin(\pi x)$$ and $$g(x) = 0$$.
💡 Hint: Use the right boundary conditions and understand how initial vibration generates the wave.
Question 2
Consider a scenario where a wave is initially at rest, moving as two waves described by $$f(x) = e^{-x^2}$$ and $$g(x) = 0$$. Describe how this will look as time evolves.
💡 Hint: Focus on how the wave shape changes with time, but the height remains constant.
