b. On the basis of your observation, did the free end of the spring have a maximum
displacement that was greater than, less than, or equal to the amplitude of the incident pulse?
c. On the basis of your answer above, were the incident and reflected pulses on the same side of
the spring (e.g., both on the cup side) or on opposite sides of the spring (e.g., one on the cup
side and one on the other side)? Explain.
In the tutorial Superposition and reflection of pulses, we developed a model that we can use
to predict the shape and orientation of a pulse reflected from the fixed end of a spring. We can
develop a similar model for free-end reflection. In this case as well, we imagine that the spring
extends past the free end. We then imagine sending a pulse with the appropriate shape and
location on this imaginary portion of spring toward the incident pulse so that, as the pulses pas:
each other, the appropriate boundary condition at the free end is satisfied.
2. Consider a pulse incident on the free end of a spring as
shown. Note that the leading edge of the pulse is 2 squares
wide and the trailing edge is 4 squares wide.
Before
11 the reflected and incident pulses be on the same
onnosite sides?
