The displacement in a string is given by the following equation:

where a, λ and ν represent the amplitude, wavelength and the frequency of the wave. Assume a = 0.1 cm, λ = 4 cm, ν = 1 sec –1. Plot the time dependence of the displacement at x = 0, 0.5 cm, 1.0 cm, 1.5 cm, 2 cm, 3 cm and 4 cm. Interpret the plots physically.
