Challenge Problems
Push your limits with challenges.
Question 1
Given an arbitrary displacement function \(f(x) = A \sin(kx)\), derive the wave function using D'Alembert’s formula assuming \(c\) = 1.
💡 Hint: Apply the wave speeds to both functions and Expand with sine identities.
Question 2
Consider a scenario where a string is fixed at both ends. Describe how you would apply boundary conditions to the general wave solution.
💡 Hint: Identify how fixed endpoints will enforce the forms of \\(f\\) and \\(g\\).
