Question

what happens when the sound waves released by a bat hit an object?
the sound waves are diffused.
the sound waves are reflected.
the sound waves are refracted.
the sound waves are absorbed.

Explanation:

Bats use echolocation. When their sound waves hit an object, the waves bounce back (reflection). Diffusion is spreading out, refraction is bending (e.g., through medium change), and absorption is taking in (not relevant here as bats rely on return signals).

Answer:

The sound waves are reflected.
