Mission WM5 Boundary Behavior of Waves - Question Group 1 Help
Diagram 1 below shows a pulse traveling through a medium and approaching a boundary with a second medium. Diagram 2 shows the appearance of the media several seconds later. In these diagrams, A is the ___ pulse, B is the ____ pulse, and C is the ____ pulse.
Definition of Incident, Transmitted and Reflected Pulse:
When a wave or pulse traveling through a medium reaches a boundary with another medium, part of the incident pulse is reflected off the boundary and part of the incident pulse is transmitted across the boundary. The incident pulse is the pulse which is approaching the boundary within the original medium. The reflected pulse is the part of the pulse which has bounced off the boundary and is traveling through the original medium. The transmitted pulse is the part of the pulse which has crossed over the boundary and entered into the new medium.
