One dimensional wave equation is
- A. d^2y/dt² = a²(d^2y/dx²)
- B. dy/dt = alpha²(d^2y/dx²)
- C. d^2y/dt² + d^2y/dx² = 0
- D. none of these
Answer: A. d^2y/dt² = a²(d^2y/dx²)
Explanation: The wave equation is d^2y/dt² = a²(d^2y/dx²). Option (b) is the heat equation, and (c) is the Laplace equation.
