h temperature and short duration of the spark produce a sudden expansion of the air through which it passes, and a compression of the surrounding air. Hence a wave of compression starts from the path of the spark which produces the sound. For greater distances the difference of potential increases… … Fig. 787 Di.itance cm.010-5 \-o 20 3-0 Volts Distancecm.
