Question 1

What is the general form of D'Alembert's solution?

u(x,t) = f(x + ct) + g(x - ct)
u(x,t) = f(x - ct) - g(x + ct)
u(x,t) = f(x,t) + g(x,t)

💡 Hint: Think of the waves moving in opposite directions.

Question 2

True or False: The wave equation is a first-order differential equation.

True
False

💡 Hint: Consider the orders of derivatives in the equation.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given an initial displacement \( u(x, 0) = e^{-x^2} \) and velocity \( \frac{\partial u}{\partial t}(x,0) = 0 \), find explicit forms for \( f \) and \( g \).

💡 Hint: Integrate the given conditions step by step.

Challenge 2 Hard

Analyze the effect of changing wave speed \( c \) on the solution form, considering \( p(x,t) = A sin(kx - \omega t) \).

💡 Hint: Use relationships between the wave parameters to detail this.
