Everything You'll Have Covered

How are echolocation and sound reflection similar?

~ Echolocation and sound reflection are one and the same. Bats emit sound waves. If the sound waves are reflected, a bat knows that there is an obstacle ahead. Dolphins make sounds and wait for the sound waves to be reflected to help them locate fish, dolphins, and other sea life.

What are some ways fishermen might use sonar?

~ By using sonar, fishermen can locate fish under water. They can also determine the depth of the water in which they are sailing.

What are some ways doctors might use reflective sound?

~ Doctors use reflective sound by using an ultrasound machine to examine irregularities of internal organs or to examine babies while they are still in the womb.
