The Rayleigh criterion for the resolving power of the eye states that two point sources of light can be distinguished as separate when the angle between them is greater than the angular resolution of the eye. This criterion is based on the ability of the eye to distinguish two closely spaced objects as separate entities. The angular resolution of the eye is determined by the wavelength of light and the diameter of the pupil. According to the Rayleigh criterion, the resolving power of the eye is limited by diffraction effects, and the smallest resolvable angle is approximately 1.22 times the wavelength of light divided by the diameter of the pupil. **

To checkmate in chess, you need to put your opponent's king in a position where it is under attack and cannot escape capture. This means the king is in a position to be captured on the next move and there are no other legal moves available to get out of check. Checkmate ends the game immediately, and the player who achieves checkmate is declared the winner. It requires strategic planning, positioning your pieces effectively, and anticipating your opponent's moves to successfully checkmate in chess. **
