Question Report Error

The frequency of a tuning fork is 512 Hz. It produces resonance in a closed organ pipe of length 16 cm (speed of sound 340 m/s). The pipe resonates in

A. End correction needed

B. First overtone

C. Second overtone

D. Fundamental mode

Answer: Option D

Solution (By JKExamLibrary)

For closed pipe, fundamental f = v/(4L) = 340/(4×0.16) = 340/0.64 ≈ 531 Hz, close to 512 Hz, slight difference due to end correction. So fundamental. Approx match, SSC type.
