What, no matter how many times it’s explained still doesn’t make any sense?

The double slit experiment. I get everything they are saying however I can never get an answer on the frequency of light produced, the accuracy of the light-particles(photons) and most importantly the width of the slits in comparison to the lights frequency followed by the space inbetween the slits. Ive never seen a concise video that touches on these aspects. It may be that I am missing the point entirely, but I would still like to see the full picture. Its like for years we were shown the bowling ball on a sheet to show gravity… only recently have I seen a version of this that is representitive of reality. Its so frustrating that these people go to great lengths of explination only to dismiss the finer details. I always wonder if this is a key reason for the limited understanding around thee amazing topics.
