Observed exchanged electromagnetic waves- light during interactions between microbes

It has been known that microbes communicate with each other through exchanging electromagnetic waves. However, we couldnt see the frequencies which microbes use. We used of two sources of light. One source was the natural source in any microscope. Second source was an special lamp. This film shows the result. It is interesting that some microbes obtain a lightening tail which strength from them to other microbes. Then, we removed second light in final of film and microbes lose this tail. Thank you of a group of international scientists for supporting projects.
