Question

Give any two examples of sound reflection?​

Answer 1

Answer:

Echo – Repetition of sound caused by the reflection of the sound wave is called an echo. Reflection of Sound Waves – The bouncing back of the sound wave on striking a surface such as a wall, metal sheet, plywood, etc. is called the reflection of the sound wave.a) Reflection of sound is used to measure the distance and speed of underwater objects. This method is known as SONAR. (b) 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.
