If a light shines through an open door into a darkened room, where does the light go to when the door is closed?

[pagey]

it is absorbed and converrted to heat by the walls and door. Any that isnt absorbed is reflected and then absorbed when it hits another wall.

Wow! Absorbed, converted and reflected! Just like me when I've had a few cans of Duff beer!

Thanks pagey!
