Anybody here experiment with braking down water into cold steam using ultrasonics?
I have seen water humidifiers and fog generators which turn water into cold steam/mist and was wondering what frequency is used?
Is there one specific frequency and how does this work on a molecular level i.e. does the specific frequency relate to molecular resonance (natural

It is just making very small droplets of water through mechanical means, you can do similar with very fine spray nozzles. The frequency is generally
chosen to be inaudible to most people.
And "cold steam" is a misnomer, it is simply a mist - a suspension of water droplets in air.

The frequency must be important because the mist will only be generated at specific frequency's

Why would that be?
The operating frequency of ultrasonic atomizers is usually at or near the resonant frequency for the structure from which the droplets are emitted.
This provides the most efficient coupling of energy. Twospoons - 2-7-2009 at 14:21
look up 'nebulizer'. frequencies from 500kHz to 2MHz. higher frequencies = smaller droplets.
