A closed organ pipe of length 'L' and an open organ pipe contain gases of densities rho(1) and rho_(2)respectively . The compressibility of gases are equalin both the pipes . If the frequencies of their first overtones are same then, the length of the open organ pipe is |
|
Answer» Solution :Frequency of first overtone is closed pipe `F=(3)/(4l_(1)) SQRT((P)/(rho_(1)))`Frequency of first overtone in open pipe `f^(1)=(1)/(l_(2)) sqrt((p)/(rho_(2))) rArr l_(2)=(4)/(3)l_(1) sqrt((rho_(1))/(rho_(2)))` |
