Where do light particles “go?”

Question

Where do light particles go? If a person is in a dark room, and they open a curtain, light illuminates the room from outside. But then, when the curtain is closed, the room is dark again, and the light is no longer there. Where did it go?

I probably have a flawed understanding of how light particles work.

Answer 1

It stopped existing. When light hits an object, some of it is reflected, and some of it is absorbed. That absorbed light stops existing and turns into heat.
