What is end correction ? Is the end correction same for a pipe open at both end and closed at one end ?

The fundamental frequency of a closed organ pipe of length 20 cm is equal to the second overtone of an organ pipe open at both the ends. The length of organ pipe open at both the ends is

The harmonics which are present in a pipe open at one end are

What is the formula for end correction in air?

If we study the vibration of a pipe open at both ends, then the following statements is not true

Show that the fundamental frequency of vibrations of the air column in a tube open at both is equal to double the fundamental frequency in a tube of the same length and closed at one end.

A pipe of lengths 10 cm, closed at one edn, has frequency equal to half the 2^(nd) overtone of another pipe open at the ends. The lengths of the open pipe is

State causes and and limitations of end correction.

Find the fundamental , first overtone and second overtone frequencies of a pipe , open at both the ends , of length 25 cm if the speed of sound in air is 330 m/s .

Distinguish between harmonics and overtones. Find the fundamental and second overtone frequencies of a pipe open at both ends of length 25cm if the speed of sound in air is 330 m//s .
