Answer 2

REFLECTION

Step-by-step explanation:

Reflection of the sound wave is its property to bounce back after striking a surface.

Since dolphins use echolocation where the emitted sound is bouncing back after striking the object which helps it to navigate the property of the sound wave is the reflection.

The reflection of the sound waves is responsible for producing echoes as an echo occur when a reflected sound wave reaches the ear more than 0.1 seconds after the original sound wave was heard.
