In the experiment Standing Waves,if you continue to lwer the water level after recording l(m) at the first sound resonance at fixed tuning fork frequency, you will hear the sound again but sound gets louder (second resonance). At this point, by what factor has l(m) increased? Why?

sorry, wrong typo...
the answer is when the water level is lower, the air in the glass tube. the changing of the L is to match the natural frequency of the air column inside the glass tube with the tuning fork that vibrate at fixed frequency. when the matching is achieve, the resonance occur which cause a louder sound
