1 Consider the pulse described in terms of its displacement at f(z,t) : + kzz-2 %3! 3 where k, and k, are constants. Draw the wave profile. Write an expression for the wave, having a speed v in the negative z- direction, as a function of time t. If v =1 m/s, sketch the profile at t= 2 s. What if k, = k2? 1 Consider the pulse described in terms of its displacement at f(z,t) : + kzz-2 %3! 3 where k, and k, are constants. Draw the wave profile.
