Question

1. a wave interaction in which a wave bounces off a surface that it does not go through is called

diffraction.
transmission.
absorption.
reflection.

Explanation:

To solve this, we analyze each term:

• Diffraction: Bending of waves around obstacles, not bouncing off.
• Transmission: Wave passes through a medium, not bouncing off.
• Absorption: Wave energy is absorbed, not bouncing off.
• Reflection: Wave bounces off a surface without passing through, matching the description.

Answer:

D. reflection (assuming the options are labeled A - D with D being reflection; if the last option is reflection, the answer is the last option labeled as, e.g., D. reflection or the option with "reflection" text)
