When interaction is disorganized, sound travels in all directions due to which phenomenon?

• A. Absorption
• B. Reflection
• C. Scattering
• D. Refraction

Answer: (C)

Scattering is the process at work here. When a sound wave meets a rough or irregular surface (or moves through a medium with many obstacles), the wavefront is broken up and redirected in many different directions. The result is sound energy that spreads outward rather than traveling along a single, predictable path. Absorption would simply reduce the sound energy without spreading it. Reflection on a smooth surface would send sound back mostly in one direction (a clear echo). Refraction changes direction when entering a different medium, but doesn’t inherently cause energy to disperse in all directions. So, the disorganized spread of sound is best explained by scattering.
