Question

matching: for each scenario described, identify which type of wave behavior the scenario represents.
an ocean wave travels through a narrow slit in a barrier and then spreads out in circular ripples on the other side. choose
two sound waves from different sources intersect and the volume of the sound becomes louder. choose
when a person yells out over a canyon, they hear an echo of their voice. choose
when light travels from air to water, it bends slightly, causing the appearance of an underwater object to distort. choose

Explanation:

1. First Scenario (Ocean wave through slit)

Wave diffraction is the spreading of waves after passing through a narrow opening (like a slit). The ocean wave passing through a narrow slit and spreading into circular ripples matches diffraction.

Wave interference occurs when two or more waves meet. Constructive interference (when waves align to increase amplitude) causes louder sound here, so this is interference (specifically constructive, but the general behavior is interference).

An echo is a reflection of sound waves. When sound hits a canyon wall (a surface), it reflects back, so this is wave reflection.

Answer:

Diffraction

2. Second Scenario (Two sound waves intersect, louder sound)
