Question

bats use a process called echolocation to navigate and find prey in the dark.
a bat emits high frequency sound waves. some of the sound waves bounce off of an object and travel back to the bat. the bat estimates how far away the object is based on how long it takes for the echo to return.
how do sound waves from a bat interact with matter during echolocation? complete the sentences.
sound waves emitted by a bat are ________ when they travel through the air.
some of the waves are ______ when they bounce off an object. these sound waves are then ______ back through the air to the bat.

Explanation:

1. Sound waves travel through air as vibrations, so they are transmitted through the medium.
2. When sound waves hit an object, they reflect off its surface.
3. After reflecting, the waves travel (transmitted) back through the air to the bat.

Answer:

Sound waves emitted by a bat are transmitted when they travel through the air.
Some of the waves are reflected when they bounce off an object. These sound waves are then transmitted back through the air to the bat.
