ok if a light reflects into a mirror.....why doesnt it make a room even brighter????i have tried this i turned on a light in my room and saw how bright it was and then i brought in a mirror and turned on the light to where it reflect into the mirror and it DOES NOT make to room any brighter....WHY

light can reach its full capacity in brightness, be refracted, reflected, but not multiplied in energy, strength or intensity.

Are you sure about that?
Did the room have white walls? White paint reflects nearly as much light as a mirror, in fact it might even reflect a bit more. A mirror absorbs some of the light and only reflects about 85% of it. A white wall will reflect perhaps as much as 90% of the light.
However if you tried the same experiment in a room with walls painted flat black I think you might find the mirror worked as you expected.

Light travels in straight line so it is also relected in a straight line from a mirror. To make a room appear bright you have to reflect light as much as possible and at the same time also scatter it in different directions. So a instead of a single plane mirror you will have to use small mirror pieces glued together (over a sphere preferably).
Brightness is also a result of materials absorbing light in UV region, while reflecting back in visible region which increases the output of visible light from the input visible light.

the mirror doesn't *add* light to the room, is one reason. Only a light source can do that.
But still, you would notice the room is brighter if all the walls were mirrors. Why is that?
Because walls *absorb* light more than mirrors do...and the walls are bigger so you would notice this difference. ('Absorb' is another way to say light disappears, in a sense...)

it doesn't make the room brighter because it is still the same amount of light, its just traveling through more space

u are not adding light just reflecting the light

It just reflects the light, it doesn't intensify it.

It looses about five percent of it's brighness through refraction. even more if the mirror is dirty!

depends on the type of mirror i think. convex, concave, or flat. i'm not sure which one will do it. also, it won't work too well during the daylight. i don't know whether you tried it then or not. :)
