intof compression, because the air both in front and behind is displacedtowards L, so that the density of the air is above the average.Similarly A and M are points of rarefaction, because the greatestseparation of the air particles occurs there. It is now possible to draw a new curve which… … Fio. 635.—Compression curve for longitudinal wave. and fh.section Consider ACE to be the axis of a cylinder of unit cross-when there is no displacement, the air within this cylinderis in a similar condition to the air outside, and the volume of airbetween two planes, at right angles to the axis and…
