3 cards from this section. Quick, good the night before a test.
What happens to a wave at a free end?
Consider how a wave would behave differently at a fixed end.
What stays the same when a wave reflects at a free end?
Think about energy conservation.
What happens to a wave when it reflects at a free end?
Remember the definition of a free end.
True or False: The amplitude of a wave changes during reflection at a free end.
Think about what happens when the wave returns.
A wave traveling on a rope reflects at a free end. If the incident wave is described by y = Asin(kx - ωt), write the equation for the reflected wave.
Remember how the wave behaves at the boundary.
Explain how the different types of boundaries (free vs. fixed) could affect energy transmission in practical applications like cables or strings.
Consider why energy loss might occur differently at each type of boundary.
