Quick Answer: The Reflection of Sound Apparatus shows that sound, like light, reflects from a hard surface, helping students relate incident and reflected sound to the law of reflection and to echoes.
Last updated: October 2026
Key Features
Demonstrates sound waves reflecting from a hard surface
Compares sound direction before and after reflection
Relates the angle of incidence to the angle of reflection
Qualitative demonstration for lessons on echoes and acoustics
About This Product
Away from background noise, the reflecting surface is set in place, the sound source is aimed at it, and the receiver, listening tube or observation position is adjusted until the reflected sound is detected. Changing the incident angle and noting how the reflected sound changes direction connects wave theory with acoustics in halls, walls and reflectors. Besides buyers across India, the Reflection of Sound Apparatus can be exported to institutions in Haiti, Paraguay, Morocco, Cabo Verde, Guinea and Yemen.
