Can 2 beams of ultraviolet light intersect and be visible where they intersect?

04 April 2017 1 764 Report

I think What you say is not possible with interference. Interference of light does not produce new colors of light. Light would have to scatter in elastically off of some molecules to produce a down-shifted frequency (Raman scattering or some type of wave-mixing phenomena). The point is, the light should interact with matter to change its frequency.
