Ernest carry out a resonance experiment by vibrating a tuning fork over a column of air as shown in the picture. The water in the tube is reduced little by little until the sound of the tuning fork is loud first when the condition is like picture (2), and the second loud sound is heard when the condition is like picture (3). If the speed of sound in air is 340 m/s, then the frequency of the tuning fork is ....
