   The reflection of Sound follows the same laws as for the reflection of Light.
   - Angle of Incidence = Angle of Reflection
   - The incident wave, The reflected wave and the normal lay in the same plane.
   
   Sound waves can be reflected by large, hard, smooth, vertical and faraway surfaces e.g walls, buildings and cliffs.
   
   Echoes are produced by the reflections of sounds from such surfaces.
