MHT CET 2025 Physics question
An air column is of length 17 cm. The ratio of frequencies of overtone if the air column is closed at one end to that open at both ends is
(velocity of sound in air = 340 )
Answer: (C)
Solution
Closed pipe: only odd harmonics, the th overtone has frequency . For the 5th overtone, . Open pipe: all harmonics, the th overtone has frequency ; for the 5th overtone, $ = 6 =
