……………… is a common opening of food pipe and wind pipe.

At the open end of organ pipe

The front opening of the wind pipe is guarded by -

[Q. Nos. 3-4] Difference in frequencies between 3rd overtone of closed pipe and 5th haronic of the same pipe is 400 Hz. Futher 3rd hormonic of this closed pipe os equal to 6th hormonic of another open pipe. Fundamental frequencies of closed pipe and open pipe are: a) 200 Hz, 400 Hz b) 150 Hz, 75 Hz c) 200 Hz, 100Hzz d) 400 Hz, 300Hz

What should be the ratio of the lengths of a closed pipe and an open pipe, so that the frequency of their First overtones are the same.

Wind pipe in man arises form

Write down the expression for the nth harmonic in (i) closed pipe (ii) an open pipe.

Which of the following prevents the entry of food into the wind pipe?

The fundamental frequencies of a closed pipe and an open pipe of different lengths are 300 Hz and 400 Hz respectively. If they are joined to form a longer pipe, the fundamental frequency of the long pipe so formed is

Draw diagrams to show the various modes of vibration in (i) an open pipe and (ii) a closed pipe.
