The speed of sound in an air column of `80 cm` closed at one end is `320 m//s`. Find the natural freqencies of air column between `20 Hz` and `2000 Hz`.

The difference between the frequencies of the first and second overtones of an air column closed at one end is 280 Hz. Find the frequency of its third overtone.

The difference betweeen the freqencies of the second and third overtones of an air column in a pipe closed at one end is 160 Hz. What is the frequency of its first overtone ?

The shortest length of resonating air column closed at one end is 7 cm when a tuning fork of frequency 480Hz is used.If inner diameter of the tube is 3 cm, find velocity of sound in air.

An electronically driven loudspeaker is placed near the open end of a resonance column apparatus. The length of air column in the tube is 80 cm. The frequency of the loudspeaker can be varied between 20 Hz and 2 kHz. Find the frequencies at which the column will resonate. Speed of sound in air = 320 m s^-1
