Two very narrow slits are spaced 1.85 μm and are placed 30.0 cm from a screen. What is the distance between the first and second dark lines of the interference pattern when the slits are illuminated with coherent light with a wavelength of 546 nm ? (Hint: The angle θ in equation dsinθ=(m+12)λ is not small.)
