A closed and an open organ pipe have same lengths. If the ratio of frequencies of their seventh overtones is ( a-1 a ) then the value of a is ________

Correct answer

0

Step-by-step solution

For closed organ pipe f _ c =(2 n +1) v 4 = 15 v 4 For open organ pipe aligned & f _ o =( n +1) v 2 = 8 v 2 & f _ c f _ o = 15 16 = a -1 a & a =16 aligned
