Is it possible to realize whether a vessel kept under the tap is about to fill with water? |
|
Answer» SOLUTION :The frequency of the note produced by an air column is inversely proportional to its length. As the level of water in the vessel RISES, the length of the air column above it decreases. It produces sound of DECREASING frequency. i.e., the sound becomes SHORTER. From the SHRILLNESS of sound, it is possible to realize whether the vessel is filled with water. `v_("min") = 11.71 ms^(-1)`. |
