Find the ratio of fundamental frequencies \( f_1/f_2 \) for a pipe open at both ends when \( \frac{1}{3} \) of its length is later submerged in water.

Determine the ratio of the speed of sound in Oxygen to that in Hydrogen at the same temperature.

A person standing between two parallel cliffs fires a gun and hears two echoes, first echo after $1$ second and the second echo after $3$ second. The distance between the two cliffs is (Velocity of sound $= 340\text{ m/s}$ )

Three tuning forks A, B and C have respective frequencies \( n_1, n_2 \) and \( n_3 \) related as \( n_1 = 1.03n_2 \) and \( n_3 = 0.99n_2 \). When A and C are sounded together 4 beats are heard per second. The frequencies of fork B and C are respectively

The fundamental frequency of a closed organ pipe of length \( 20 \, \mathrm{cm} \) is equal to the second overtone of an organ pipe open at both ends. What is the length of the organ pipe open at both ends?
