asticbodies ; that is, they return upon themselves, forming new concentric waves,which seem to emanate from a second centre on the other side of the obstacle.This phenomenon constitutes the reflection of sound. Fig. 212 represents a series of incident waves reflected from an obstaclePQ. Taking, for… … If any point C of the reflecting surface be joined to the centre of sound,and if the perpendicular CH be let fall on the surface of this body, the angleACH is called the a7igle of incidence, and the angle BCH, formed by theprolongation of czC, is the angle of reflection. The reflection of sound is…
