Before looking at the three movies on this page, you might like to look at two web pages which explain the context. The first web page shows a reconstruction of Faraday's original experiment (click here for movies); and the second web page explains the process of producing such waves on a bubble (click here for movies).
The three movies on this page show a bubble as the amplitude of excitation increases. On the left a single mode, the Faraday wave, is excited (the zero-to-peak acoustic pressure amplitude is 24 Pa). In the middle frame, an increase in the amplitude of the driving acoustic field has caused more modes to be excited (the zero-to-peak acoustic pressure amplitude is 44 Pa). On the right, so many modes have been excited that the bubble fragments (the zero-to-peak acoustic pressure amplitude is 139 Pa). The mean radius of the bubble is ~2.1 mm. The driving field has frequency 1.5006 kHz. |
