I'm on a timer
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?
1 the generated sound wave will not be able to reflect off of the object.
2 the sound wave will not be generated, so there will be no echoes received.
3 the echoes will be made but will not be able to be received by the machine.
4 the machine will not be able to process the received echoes into images.

The generated sound wave will not be able to reflect off of the object.

Explanation:

Ultrasound may be defined as the sound waves that has the frequency range larger than 20,000 Hz. This sound range is inaudible to human ears but can be detected by the animals like bats.

Ultrasound is used in the medical application as well. The kidney stones can be detected by using the ultrasound. The rays can be detected back if there is any chances of hurdles or possibility of stones in the kidney. If the kidney is normal no ultrasound waves will be deflected back.

Thus, the correct answer is option (A).

micro/nanoscale topography surface exhibits many prominent properties and is extensively employed in biomedical device, microfluidic device and energy device fabrication. additionally, the clinical applications of biomaterials can be largely expanded with of nanostructured surfaces.
