Do perfectly aligned opposing light waves with matching light frequencies and wavelengths cancel each other out like sound waves do, and what does this look like from the side? - and if there's a detectable or visible effect, can we change the center where the clashing or wavelenght cancelation occurs?

And if there was a effect visible mid air exactly where the cancelation occurred, maybe we can move the effect left and right, to create a 3D matrix from two identical opposing [and inverted] 2D matrices? like maybe we can't have photons reflect mid air off of nothing, but we might be able to stop visibility of the photon or its visible wave mid air, on a highly specific distance between two opposing wave cancelation plates?

perhaps by introducing a small delay in the timing between the two screens, send one red photon from the left and send one red photon from the right, but a fraction later, so that the photon from the left will have moved a little more than half the distance between them. the distance where we want them to collide can be calculated by a single 2D back matrix as well.if cancelation could be manipulated then two opposing laser projectors could form a more 3dlike image between them perhaps. maybe these modern short throw projectors, when placed correctly could do the job. and if two projectors can, so can 4?
