Explain the difference between longitudinal and transverse waves. Give an example of each kind. In Eqs 16.1 and 16.2, why does y(x, t) = f(x - vt) represents a wave traveling to the right (+x-axis) and y(x, t) = f(x + vt) represents a wave traveling to the left (-x-axis)? In Section 16.2, two speeds are mentioned. One is the wave speed, given by v=Xf and the second speed it the transverse speed, given by dy dt Clarify the difference between the two. Vy = -wA cos(kx - wt). (16.12) (16.12)
