In the game of baseball, the catcher uses his fingers to send a sign to the pitcher, telling what pitch to throw next. some center fielders claim that they can tell if a catcher show one finger or two fingers to the pitcher. The center fielder is 75 m from the catcher. The Rayleigh criterion can be used to determine if the center fielders resolution limit is good enough to distinguish different signs. Using the Rayleigh criterin what is the approximate smallest resovable separation of the catcher's fingers?
