Scientists used an all-optical method to detect and dynamically track the natural vibrational frequencies of a microorganism ...

Today, a standard demonstration is to excite the plate with a single frequency tone generator that continually rises in frequency. When it corresponds to a mode of vibration in the plate, the nodal ...

A sound wave is a vibration that travels through a solid, liquid or gas such as the air or water. A loud sound has a large amplitude, a high pitched sound has a high frequency. Musicians and ...
