Question

The minimum distance through which one tube, in a Quincke's tube,
is to be shifted within the other, in order to get two such
positions when no sound is heard, is 16 6 cm Determine the

Dear Student,

λ2=Distance between 2 consequtive maximas or minimas
Point of no sound is a minimaor λ=2×16
6=33 2 cm=0 332 mf=vλ⇒3320
332=1000 Hz
