what happens to the sound wave in echolocation?\nit releases energy\nit is reflected\nit is refracted\nit is…

Brief Explanations:

In echolocation, sound waves are sent out and bounce back. This bouncing - back is the process of reflection. Energy release is not the main characteristic of sound waves in echolocation. Refraction involves the bending of sound waves as they pass from one medium to another which is not the key process in echolocation. Absorption means the sound wave's energy is taken in by a medium, which is not what echolocation is based on.

Answer:

It is reflected
