when the player would come back from an injury
Equilibrium is a state of balance. When one factor increases, it would also be necessary for an opposing factor to increase to maintain balance. Reversibility allows for the decrease of factors to maintain this level.
Here's the way I see it: Optical reversibility means that if a light passes through a medium with an index of refraction, n, and the light hits that medium at a certain angle, the angle of incidence, the light refracts and comes out at a different angle than the angle of incidence. In other words, if light hits a refracting medium at 10 degrees to the normal, it will refract and come out at 7 degrees to the normal. Then, if it were switched, and the light were made to hit the refracting medium at 7 degrees to the normal, then it would refract and come out at 10 degrees to the normal. This is optical reversibility as seen in refraction. In reflection, however, the angle of incidence and the angle of reflection is the same. If light hits a reflecting medium at 10 degrees, it will reflect at an angle of 10 degrees. So if the angles were switched in this case, it would do nothing, it would just hit the reflecting medium at 10 degrees and again be reflected at 10 degrees. So, does the principle of optical reversibility hold for reflection as well as refraction? It depends on if you view switching the position of the same number to be reversing anything or not. Actually the principle holds good for every optical system in geometric optics....
No. Perform is a verb. A performer would be a noun.
reversibility is when you have been njured or taken a break from whatver sport,within that break your fitness level would of dropped because your body aint doing any exercise,and its harder for your body to regain fitness level than lose it.
One who performs, accomplishes, or fulfills; as, a good promiser, but a bad performer; especially, one who shows skill and training in any art; as, a performer of the drama; a performer on the harp.
An antonym would be: performer.

That would be Michael Jackson.
It's beginner's luck. When someone with little experience in something performs something better than they're experience would normally allow. For instance, a novice golfer scoring less than 100 on one of their first games.
