I have a question regarding light. Say we have a light source such as a lazer beam. If we arrange mirrors in a certain way so that when the lazer is turned on it will reflect through the mirrors constantly, because the mirrors will be placed in a special way. If we turn the lazer off, will the light still be there. I think it still should be relefting but I was just curious

    Sure. The only problem is your mirrors aren't perfect, so at least a few photons will be absorbed or scattered on each pass, so your light will disappear sooner or later.
