Question

A sinusoidal wave travelling in the positive x-direction on a stretched string has amplitude 2.0 cm, wavelength 1.0 m and velocity 5.0 ms^–1. The initial conditions are: y = 0 and ∂y/∂t < 0 at x = 0 and t = 0. Find the wave function y = f (x, t).

Answer 1

The general form of a wave travelling in the positive x direction is
