Question
Give two practical applications of reflection of sound waves.
Answer
Two practical applications of the reflection of sound waves are:
Megaphones (or Loudhailers): These are designed to reflect sound waves repeatedly so that they travel in a specific direction without spreading out, making the sound travel farther.
Stethoscope: It is a medical instrument used for listening to sounds produced within the body (mostly heart or lungs). The sound of the heartbeat reaches the doctor’s ears by multiple reflections within the stethoscope tube.
