if we want to trap the light between then for infinitely long time?
The distance between the mirrors is 1m.

That's interesting. The radius of curvature would also depend on the mirror's diameter, so no light escapes. I would think the mirrors would have to be identical.

Two PARALLEL concave mirrors? Well, they they'd have to be concentric spheres, so that the difference in radius is 1 m. But having a pair of mirrors bounce a light beam "indefinitely" is a common problem in laser design. Usually, though, the concavity is opposite, not parallel. The problem is made complicated by the fact interference effects are taken into consideration.
A trivial arrangment is to have one plane mirror and the other one concave. Then, roughly, the radius of curvature is 1/2 m.

Say Bloody Mary three times in a row in a pitch black room and see what happens!
