Some of the appearances of theflame frequently met with aregiven in Fig. 653. A is that dueto an organ pipe blown gently,and B that due to the same pipe blown hard, so that the frequencyis doubled. Interference produced by a divided tube.—A tuning fork F (Fig. 654)of fairly high frequency is Bounded opposite the opening A of a tubeAB. The compression waves travelling down AB, enter the tube CBD
