Correction to the Blog of December 14, 2011

There was an error in the chart showing cavitation bubble size vs. ultrasonic frequency in the blog published on December 14, 2011.  The bubble size was incorrect by an order of magnitude.  The correction can be seen at

Ultrasonics – Number and Size of Cavitation Bubbles

I apologize for the error and any mis-understandings it may have caused.
