Stationary wave of frequency 5 K Hz is produced in a tube open at both ends and filled with air at `300 K`. The tube is oscillating in its first overtone mode. (a) Find the length of the tube assuming that air contains only nitrogen and oxygen in molar ratio of `3 : 1`. (b) What shall be the frequency of sound wave used so that the same tube oscillates in its second overtone mode?
