are we able to basically talk about ray like photons photons going alongside an axis, or can we are looking to talk about full 3D modes which are  matlab  eigen modes  engineering   matlab  cavity. However in both case this seems bananas to me. if two photons are canceling it’s  matlab  same as no photons. the energy did not disappear, matlab  just was meditated at  matlab  time you injected  matlab  2nd photon. you don’t get two photons co propagating out of section like they claim. If two out of phase photons, carrying momentum, cancel each other out and ‘stop to exist’, what came about to  matlab  momentum?If that, too, ceased to exist, and all  matlab  cancelled photons were getting into  matlab  same path, matlab  could have  engineering   net outcome on  matlab  momentum  engineering   matlab  force.
