2 cards from this section. Quick, good the night before a test.
What happens to a wave at a rigid boundary?
Think about how a wave 'flips' over.
What is a node in a standing wave?
Where does a string not move at all?
What type of wave reflection occurs at a rigid boundary?
Think about how waves behave when they encounter a hard surface.
True or False: At an open boundary, the reflected wave undergoes a phase change.
Consider how waves behave differently at open ends.
A wave described by the equation y = 0.5 sin(3x - 5t) hits a rigid boundary. Write down the equation of the reflected wave.
Consider the phase change that occurs upon reflection.
Describe the formation of standing waves in a tube with one end open and the other closed. Identify the nodes and antinodes.
Relate it to the boundary conditions and the nature of wave reflections.
