Solution

Stethoscope working and principle:

  1. The air-filled stethoscope tube has a diaphragm on one end.
  2. This diaphragm vibrates when it is placed on the patient's chest because the sound coming from the chest is muffled.
  3. These vibrations are sent through an air-filled tube, where they are amplified by many reflections off of the tube's interior walls.
  4. The numerous reflections theory underlies how the stethoscope operates.
  5. The surface of the medium, which might be solid or liquid, is where the sound is reflected.
  6. The surface can be large and either rough or polished for sound reflection.
  7. A stethoscope's operation is also based on the way sound reflects off surfaces.
  8. The sound of a patient's heartbeat is picked up by a stethoscope through several reflections of sound.

Final Answer: A stethoscope works on the principle of different reflections of sound.
