Tone Generator

Greetings,

Tone Generator app generates pure sine wave tones at frequencies from 20hz to 22,000hz.src

Ok, tone generator is an easy to use application which will handle the lowest/highest frequency of tones and it will provide you help with the adjustments of tunes. How can we use tone generator in science experiments? I guess this is a big feature of this application. have fun and love music because music is life.
