This is effectively how a fibre optic works.
How many times would a light ray be reflected inside a circular mirror?//www.youtube.com/watch?v=VnZ6UdAEzbYLet's say we have a circular mirror which is reflective in inner side. A laser beam is shone through a small hole on the mirror. How many times the laser beam would be reflected, if the incoming angle is 10 degrees?
I think the answer will depend upon the quality of the mirror; even tiny losses will quickly turn all of the energy in the photons into heat.
So, not actual science then...

It would be a math problem if the mirror was a polygon.

Because it stops working.If a beam of light hits a curved surface, it's no longer a beam.
Diffraction stops it being scientific.
