Question

an ultrasound tech is trying to identify an object, but the machine is broken and is not sending out the sound wave. 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 be unable to be received by the machine. the machine can process echoes into images, but with the broken screen, they cant be displayed.

Explanation:

Ultrasound machines work by generating sound waves. These sound waves travel, reflect off objects (echoes), and then are received by the machine. If the machine isn't sending out sound waves (sound wave not generated), there are no waves to reflect (so no echoes are formed in the first place).

• Option 1: Incorrect because no sound wave is generated (not about reflection issue of a generated wave).
• Option 2: Correct as no sound wave generation means no echoes (since echoes are reflections of the sound wave).
• Option 3: Incorrect as no echoes are made (due to no initial sound wave).
• Option 4: Problem is with sound - wave generation (not screen display).

Answer:

The sound wave will not be generated, so there will be no echoes received.
