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.

two sound waves from different sources intersect and the volume of the sound becomes louder.

options: diffraction, interference, refraction, reflection (with an image showing the option selection dropdown)

Explanation:

For the first scenario (ocean wave through narrow slit):

Diffraction is the bending or spreading of waves after passing through a narrow opening or around an obstacle. The ocean wave passing through a narrow slit and spreading out as circular ripples matches the definition of diffraction.

Interference occurs when two or more waves overlap. Constructive interference (when waves are in phase) can increase amplitude, leading to a louder sound here as two sound waves intersect and the volume increases.

Answer:

Diffraction

For the second scenario (two sound waves intersecting, louder sound):
