1.	The frequency of vibrating air column in closed organ pipe is n. If it length be boubled and radius halved. Its frequency will be nearly :
Answer» `(n)/(2)` `4n` n `2n` Solution :For a closed organ pipe, `n=(v)/(4L) rArr n PROP (1)/(L)` If `L=2L` Then `n' prop (1)/(2L)` `(n')/(n')=(L)/(2L)` (or) `n'(n)/(2)` Radius has no effect on frequency.
