MCQ
The first overtone in a closed pipe has a frequency
  • A
    Same as the fundamental frequency of an open tube of same length
  • B
    Twice the fundamental frequency of an open tube of same length
  • C
    Same as that of the first overtone of an open tube of same length
  • ✓
    None of the above
✓

Answer

Correct option: D.
None of the above
d
(d)First overtone for closed pipe = $\frac{{3v}}{{4l}}$
Fundamental frequency for open pipe = $\frac{v}{{2l}}$
First overtone for open pipe = $\frac{{2v}}{{2l}}$.
