The elimination of acoustic waves (2)
{"Image DocumentName": "The elimination of acoustic waves (2)", "Image ImageDescription": "In eq. (32) n2 and n3 occur in the combination (n2-n3) which. vanishes in the exact equation (i.e. when n1= n2= n3= n4 =1). (32) => A spurious term will arise in (32) if we set n2 to zero but not. n3 or vice-versa! => We have to set always n2 = n3! Anelastic approximation is n2=0 & n3=0!
