How can we derive or prove the principle of optical reversibility from more basic principles?

I guess I meant something different. I am talking about the fact that, light traces back its traversed path if it is made to travel backwards.
How can we prove this result?

Acut said:@Petr Mugver: I don't agree with your reasoning.
First, it is limited to isotropic media.
Acut said:Second, you haven't proved that the time it takes in one direction is equal to the time it takes in the reverse direction. Who said that the index of refraction is direction-independent? (As we all know, it isn't, but we know that from experiments only)
Acut said:By the way, if A sees B, B doesn't necessarily sees A. This is a common mistake. Have you seen those security glasses? Although the path light takes is the same in the two directions, light intensities may be different.
The principle of optical reversibility states that light rays will follow the same path when traveling in either direction through a given optical system.
This principle can be proved through several experiments, including the use of a double slit apparatus or a Michelson interferometer.
The principle of optical reversibility is important because it allows us to make accurate predictions and measurements in optics, and it is a fundamental concept in the study of light and its behavior.
While the principle of optical reversibility holds true in most cases, there are some exceptions, such as when dealing with non-linear optical systems or in the presence of strong magnetic fields.
The principle of optical reversibility is closely related to the laws of conservation of energy and momentum, as well as the principle of time reversal symmetry in classical mechanics.
