elastic bodies; that is, they return upon themselves, forming newconcentric waves, which seem to emanate from a second centre on the otherside of the obstacle. This phenomenon constitutes the reflection of sound. Fig. 225 represents a series of incident waves reflected from an obstacle,PQ. Taking… … If any point, C, of the reflecting surface is joined to the centre of sound,and if the perpendicular CH is let fall on the surface of this body, the angleACH is called the angle of incidence^ and the angle BCH, formed by theprolongation of <^C, is the angle of reflection. The reflection of sound…
