Dolphins use echolocation to hunt for prey. Which statement best explains how this application uses wave behavior?

Question

Echolocation relies on refracted waves to measure the proximity of objects.

Echolocation relies on reflected waves to determine the color of objects.

Echolocation relies on absorbed waves to determine the size of objects.

Echolocation relies on reflected waves to measure distance away from objects.

Answer 1

The statement that best explains how echolocation uses wave behavior is:

Echolocation relies on reflected waves to measure distance away from objects.

Dolphins emit sound waves that travel through the water, bounce off objects (like prey), and return to the dolphins. By timing how long it takes for the sound waves to return, dolphins can determine the distance to the objects.
