摘要: 用交变光波照射一个半涂黑玻璃瓶,可听到瓶中发声.其物理原因是交变光能激发了瓶中的一个声波共振模。

关键词: 声驻波, 共振模式, 富氏级数

Abstract: When an alternating light irradiate on a transparent glass bottle with a half inner wall coated by black regalia,a sound in the bottle can be heared. The reason is that the light produce heat which excites a sound resonance mode of the bottle.

Key words: sound standing waves, resonance modes, Fourier series
