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

Options:

Answer:

Solution:

$y (x, t) = \frac{a}{{(x \pm v t)}^{2} + b}$ is another form of progressive wave equation propagating with a speed v. Negative sign to be taken for propagation along + x-axis and positive sign to be taken for propagation along $-$ x-axis.0
