A source of vibration motion of an object is normally a source of sound. A sound of a single frequency is called Tone. 8242017 i The incident sound wave the reflected sound wave and normal at the point of incidence lie in the same plane. Since the speed of sound in air is 344 ms the distance travelled by sound in 0I s 344 ms x 01 s 344 m So to hear an echo clearly the minimum distance of the reflecting surface should be half this distance that is 172 m. 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 Echo When we hear the same sound again and again in a medium it is called Echo.
