An ultrasound machine is being used to try to identify potential kidney stones. The machine is working properly and no kidney stones are found.
Which statement best describes this situation?
The generated sound wave will not be able to reflect off of the object.
The sound wave will not be generated, so there will be no echoes received.
The echoes will be made but will not be able to be received by the machine.
The machine will not be able to process the received echoes into images.

Which would be the best title for these notes?
Echolocation
Ultrasound Technology
Digital Signal
Analog Signal
What happens when the sound waves released by a bat hit an object?
