Two monoatomic ideal gases 1 and 2 of molecular masses m1 & m2  respectively are closed in separate containers kept at same temperature. The ratio of speed of sound in gas 1 to that in gas 2 is given by

a
m1m2
b
m2m1
c
m1m2
d
m2m1

detailed solution

Correct option is B

Speed of sound in gas v = γRTM ∴v1v2 = m2m1

A tube of certain diameter and of length 48 cm is open at both ends. Its fundamental frequency of resonance is found to be 320 Hz. The velocity of sound in air is 320 m/s. One end of the tube is now closed, considering the effect of end correction, calculate the lowest frequency of resonance for the tube (in Hz).
