Answer :

Answer:

In ray optics, the mathematical formula describing the behavior of a mirror is based on the law of reflection, which states that the angle of incidence θi is equal to the angle of reflectionθr .

For a flat mirror, the formula is:

θi = θr

This equation relates the distances of the object and the image formed by the mirror to its focal length.
