Reflection of Sound Apparatus
Product Code : SCL-PMP-11222
Quick answer: The reflection of sound apparatus shows that sound reflects from a surface in the same way as light: sound sent toward a reflector along one path is heard most strongly along a second path at an equal angle. It is a qualitative demonstration for teaching the laws of reflection of sound and echoes. Lab Exports manufactures it in Delhi for schools, colleges and universities.

How the reflection of sound experiment is done
Sound, like light, obeys two laws of reflection: the angle of reflection equals the angle of incidence, and the incident ray, the reflected ray and the normal to the surface lie in the same plane. In the classic school experiment, sound from a faint, steady source travels along one path toward a hard reflecting surface, and a listener searches along a second path on the other side of the normal for the direction in which it is heard most clearly.
- Set the apparatus on a stable table in a quiet room.
- Position the reflecting surface and the two sound paths according to the apparatus arrangement.
- Place a steady, faint sound source, such as a ticking clock, at the end of the incident path.
- Move the listening path until the sound is loudest, keeping a screen between source and ear so that only reflected sound is heard.
- Compare the angles of the two paths measured from the normal.
The loudest position is found where the two angles are equal, which verifies the law. The same idea explains echoes, whispering galleries and the shaping of halls and sound boards.

Frequently asked questions
What are the laws of reflection of sound?
The angle of reflection equals the angle of incidence, and the incident sound, the reflected sound and the normal at the point of incidence lie in one plane.
Is the reflection of sound experiment quantitative?
It is mainly qualitative: students identify the direction in which reflected sound is strongest and compare it with the incident direction.
