A closed pipe is suddenly opened and changed to an open pipe of same length . The fundamental frequency of the resulting open pipe is less than that of 3rd hoarmonic of the earlier closed pipe by 55Hz. Then , the value of fundamental frequency of the closed pipe is

1.	A closed pipe is suddenly opened and changed to an open pipe of same length . The fundamental frequency of the resulting open pipe is less than that of 3rd hoarmonic of the earlier closed pipe by 55Hz. Then , the value of fundamental frequency of the closed pipe is
Answer» `165Hz` `100HZ` `55Hz` `220Hz` Solution :`(n_(C1))/(n_(03))=(3)/(2)impliesn_(C1)=(3)/(2)n_(03)n_(C1)=n_(03)-55`
