Why can you make water sltc3jc v:bvf(1 ,wbf ix.1s(kts+dug .ck--n50 /bf oonkhwu75nd3o ;j)h yvuosh back and forth in a pan only if you shake the pan a)dfou7hj n/05-; noownv5yuc3k- hbkt a certain frequency?
参考答案:
To make the water “slosh”, you must shake the water (and the pan) at the natural frequency for water waves in the pan. The water then is in resonance, or in a standing wave pattern, and the amplitude of oscillation gets large. That natural frequency is determined by the size of the pan – smaller pans will slosh at higher frequencies, corresponding to shorter wavelengths for the standing waves. The period of the shaking must be the same as the time it takes a water wave to make a “round trip” in the pan.
