light is needed to reflect an image off a mirror...no light no reflection

A parallel light source will reflect off a concave mirror and go through a point inside the curve called the focus. Reflecting from a convex mirror will cause all light to bounce off in a straight line away from a focus point behind the mirror.

the same amount of candle light that of wich the candle is emmiting.
Because it has a shiny & smooth surface which helps to reflect the light... Take an example of tree. A tree have a rough surface due to which light can be reflect. So All of this depends on the smoothness of surface.. :-)
It reflects at like 45 degrees I think. No, it reflects off at the same angle it hits the mirror. If the light wave hits the mirror at a 30o angle on the left side, it will reflect off at a 30o angle on the right side. Scientists usually measure these angles from an imaginary line perpendicular to the mirror at the point where the light wave hits the reflecting surface; sounds awkward, but it makes the math easier.
