Beams of light

    what happens when two beams of light pass through each other perpendicular to each other??

    Nothing: light (photons) does not interact with itself. Thus the two lightbeams will simply go strait through eachother.

    It depends if the beams were coherent or not. But two beams passing perpendicularly wouldn't be affected either way as the field components would be in the wrong directions
