>>12149468is not meaningless, but you have to realise first of all that a ray is a continuous "beam" of something in this case is light so your question could be reframed as: how much energy a laser has? and fto know that you'll have to see what color the laser is and this will give the aproximate frequency then you could use plancks equation to get how much that "single ray" or laser's energy is emitting PER SECOND, this is the next important thing a ray by definition happens over a period of time
on the other hand you might not know what a ray was and you are using the wrong term for what you really meant to ask
