Question

multiple-choice question
waves passing through an opening results in ____.
reflection
refraction
interference
diffraction

Explanation:

To solve this, we analyze each option:

• Reflection: Waves bounce off a surface, not pass through an opening. Eliminate.
• Refraction: Waves bend when entering a new medium, not related to passing through an opening. Eliminate.
• Interference: Result of two or more waves overlapping, not from passing through an opening. Eliminate.
• Diffraction: Defined as waves spreading out when passing through an opening or around an obstacle. This matches the scenario.

Answer:

D. diffraction
