Reflection of Sound



                                               Laws;
                        1.The incident sound wave, the reflected sound wave
                              and the normal, all lie in the same plane.
                       2.The angle of incident of incident sound wave is equal
                       to the angle of reflection formed by the reflected sound
                                         wave, that is, i = r
