Using Sound

Question 2 • Fall 24 GSE Physical Science B IC

Which statement describes how echolocation and ultrasound imaging are the same?

Answer
A
They both use the absorption of sound waves.
B
They both use the diffraction of sound waves.
C
They both use the reflection of sound waves.
D
They both use the transmission of sound waves.

Explanation

Echolocation works by sending out sound waves and detecting the echoes that bounce back from objects. Ultrasound imaging also sends sound waves into the body and uses waves reflected from tissues to create an image. Therefore, both rely on the reflection of sound waves; absorption, diffraction, and transmission are not the shared process described here.
