Reflected sound waves are called echoes.
A stethoscope consists of two equal-length tubes of air, physicallyjoined, which conduct sound waves to the examiner's ears.

echo!
it is based on the pricipal of reflection and amplification of sound waves.
Reflected sound waves are called echoes. This occurs when sound waves bounce off a surface and return to the listener's ears, creating a delayed repetition of the original sound.
Light waves: when light hits a smooth surface, it can be reflected. Sound waves: sound can bounce off hard surfaces such as walls, resulting in reflection. Water waves: waves in the ocean or a pond can be reflected off a barrier or shore.
Sound waves can be reflected when they encounter a surface that is smooth and hard, causing the waves to bounce off the surface and change direction. This reflection of sound waves allows them to travel in different directions and be heard from various angles.
When a doctor or nurse places a stethoscope diaphragm on a patient's chest, sound waves traveling through the patient's body cause the flat surface of the diaphragm to vibrate.When a doctor or nurse places a stethoscope diaphragm on a patient's chest, sound waves traveling through the patient's body cause the flat surface of the diaphragm to vibrate.
Sound waves are longitudinal waves; they travel from side to side, not up and down like transverse waves.

The function of the tubing in a stethoscope is to magnify the sound waves by making them narrow enough to be heard at an accurate timing through the ear canal.
