Two closed pipes have the same fundamental frequency.One is filled with oxygen and the other with hydrogen at the same temperature. Ratio of their lengths respectively is

The ratio of fundamental frequencies of an open organ pipe and a cloed organ pipe of same length at same temperature is

One of the two vessels of same capacity is filled with oxygen and other is filled with helium of same mass. Both gasess are at same temperature. The ratio of pressure of these gases is

An open and a closed pipe have same length ratio of frequencies of their nth overtone is

The fundamental frequency of an open and closed organ pipe of the same length is in the ratio

An open and a closed pipe have same length . The ratio of frequency of their n th overtone is

A closed organ pipe and an open organ pipe are tuned to the same fundamental frequency. The ratio of their lengths is

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.
