Question

Give two practical applications of reflection of sound waves.

Answer 1

Reflection of sound waves.

1. The phenomenon of sound reflection occurs when a traveling sound wave hits an obstruction causing it to return in a different direction.
2. The angle of incidence of the sound wave is always equal to the angle of reflection of the sound wave.
3. The phenomenon of echo occurs due to the reflection of sound.

Applications of reflection of sound waves.

1. The distance and speed of underwater objects are measured using sound reflection. SONAR is the name for this technique.
2. A stethoscope's operation is likewise based on sound reflection. The sound of the patient's heartbeat enters the doctor's ear through various reflections of sound in a stethoscope.
