At $t = 0$ , a transverse wave pulse in a wire is described by the function $y = \frac{6}{x ^{2} - 3}$ where $x$ and $y$ are in metre. The function $y (x, t)$ that describes the wave equation if it is travelling in the positive $x$ direction with a speed of 4.5 m s⁻¹ is:

Options:

Answer:

Solution:

A pulse moving to $+ x$ at speed $v$ is obtained by replacing $x$ with $x - v t$ in the shape function. This gives $y = 6/ [(x - 4.5 t)^{2} - 3]$ .
