A sinusoidal wave traveling in the negative x-direction (to the left) has an amplitude of 20.0 cm, a wavelength of 35.0 cm, and a frequency of 12.0 Hz. The transverse position of an element of the medium at t= 0, x = 0 is y = —3.00 cm, and the element has a positive velocity here. We wish to find an expression for the wave function describing this wave.
(a) Sketch the wave at t = 0.
(b) Find the angular wavenumber k from the wavelength.
(c) Find the period T from the frequency.
Find
(d) the angular frequency to and
(e) the wave speed v.
(f) From the information about t = 0, find the phase constant.
(g) Write an expression for the wave function y(x, 0).
