what is it called when a sound wave is slowed by a new medium?
absorption
reflection
transmission
echo

Explanation:

To solve this, we analyze each option:

• Absorption: Involves sound energy being absorbed, not slowing. Eliminate.
• Reflection: Sound bounces back, not slowing. Eliminate.
• Transmission: When sound travels through a new medium, its speed can change (slow down) due to medium properties. This matches.
• Echo: Is a type of reflection (delayed), not about slowing. Eliminate.

Answer:

C. Transmission
