Answer

Brief Explanations:

Ultrasound uses high - frequency sound waves. These waves are generated by a machine and reflect off objects. The echoes are then processed into images. Reflection, not refraction, is the key process in ultrasound imaging. Low - frequency sound waves are not used in ultrasound.

Answer:

High - frequency sound waves are generated by a machine and reflected off of objects, creating echoes that are processed into images.
