Organ pipes

The frequency of the first overtone of a closed organ pipe is same as that of first overtone of an open organ pipe. What is the ration of their lengths?

Assertion: The fundamental frequency of vibration of an open organ pipe remains same if the radius of the pipe is doubled. Reason: Frequency of vibration of an open organ pipe is independent of the radius of pipe.

A closed organ pipe of length L and an open organ pipe contain gases of densities rho_1 and rho_2 resp. The compressiblity of gases are equal in both pipes. Both pipes are vibrating in first overtones with same frequency. The length of open organ pipe is

A closed organ pipe of radius r_(1) and an open organ pipe of radius r_(2) and having same length 'L' resonate when excited with a given tuning fork. Closed organ-pipe resonates in its fundamental mode where as open organ pipe resonates in its first overtone, then :-

STATEMENT-1: An open organ pipe can be used as a musical instrument but not a closed organ pipe. STATEMENT-2: The fundamental frequency of an open orgna pipe is twice the fundamental frequency of a closed organ pipe of the same length.

Assertion: An open organ pipe of certain length has the same fundamental frequency as closed organ pipe of half the length. Reason : In case of an open organ organ pipe, at both the ends antinodes are formed while in case of closed organ pipe, at one end antinode and at the other end node is formed.

Why is the sound produced by an organ pipe open at both ends is better than that of an organ pipe closed at one end ?

Why is note produces by an open organ pipe sweeter that that produced by a closed organ pipe of same length?
