(c) Draw the velocity distribution (a graph of as a function of x) at t = 5 s for the part of the string where the velocity is nonzero.
2. Wave transmission across a boundary. String 1 with wave speed v1 is connected to
string 2 with wave speed v2. A square pulse of width W is incident from string 1 onto the
boundary between strings. Physics 2214, Spring 2012 1 Cornell University (a) Sketch the reflection coefficient R and transmission coefficient T for this pulse as a
function of the ratio v2/v1. Label important magnitudes.
(b) Can the transmitted wave amplitude be larger than the incident amplitude? If so, when,
(c) Can the reflected wave amplitude be larger than the incident amplitude? If so, when and
(d) You notice that the transmitted pulse appears to be roughly half as wide as the incident
pulse. Will the reflected pulse have the same sign or be inverted relative to the incident
