Answer:
Reflection of sound is used to measure the distance and speed of underwater objects.
This method is known as SONAR.
Working of a stethoscope is also based on reflection of sound.
In a stethoscope, the sound of the patient's heartbeat reaches the doctor's ear by multiple reflections of sound.
