Two thin parallel slits that are 19.5 latex: \muμm apart are illuminated by a laser beam of wavelength 585 nm. the interference pattern is observed on a very distant large screen. what it the total number of bright fringes (those indicating complete constructive interference), including the central fringe and those on both sides of it? solve this problem without calculating the angles! (hint: what is the largest that latex: \sin\thetasin ⁡ θ can be? what does this tell you is the largest value of m? )
