And the final one, shown below, is at t = 0.010 s. (c) The wave can be written as ( , ) sin( ) m yxt y kx t ω =+ , where / vk = is the speed of propagation. From the problem statement, we see that 2 / 0.40 5 rad/s ωπ π == and 2 /80 / 40 rad/cm k ππ . This yields 2 2.0 10 cm/s 2.0 m/s v = (d) These graphs (as well as the discussion in the textbook) make it clear that the wave is
