Reflection of Sound | Science Experiment

🔍 What is This Setup?

This is a sound wave direction experiment setup—commonly used in physics classrooms to demonstrate the reflection of sound waves and verify the law of reflection using:
• Two hollow pipes or tubes
• A semicircular protractor base

📐 Concept Demonstrated:

✅ Law of Reflection of Sound:

Angle of incidence = Angle of reflection

One pipe (on the left) is likely used to transmit sound (source). The other pipe (on the right) is used to receive sound (detector/ear).

📌 Key Teaching Points:

1. Sound travels in a straight line.
2. Sound reflects off surfaces like light.
3. Angle of incidence = Angle of reflection for sound waves.
4. Used in real-world applications like parabolic microphones, auditoriums, and sonar systems.
