Use the figure. Straight wavefronts pass the end of a barrier and spread into the region behind it. Which wave behavior is shown?
Use the figure. Wavefronts cross a boundary and change direction as their spacing changes. Which behavior is shown?
Use the figure. Two coherent sources make overlapping circular wavefronts. Which behavior creates the pattern of large and small disturbances?
Use the figure. Circular wavefronts are crowded in front of a moving source and spread out behind it. What effect is shown?
Use the figure. The wave on a fixed string has points that stay still and loops that vibrate in place. What pattern is shown?
Use the figure. One upward pulse and one downward pulse move toward each other. What behavior occurs when they overlap?

Two identical upward pulses on a spring arrive at the same place at the same time. What happens at that instant?
An upward pulse and an equal downward pulse overlap completely on a rope. What does superposition predict?
A student hears a band around a corner, even though a wall blocks the direct line of sight. Which behavior lets sound spread there?
A siren moves toward a stationary listener in still air. Which effect is heard, and what changes?
A swing is pushed once every natural period, and its motion grows larger. Which wave idea describes the growth?
