A pair of slits, separated by 0.200mm, is illuminated by light having a wavelength ofλ = 592 nm. Aninterference pattern is observed on a screen 130 cm from the slits. Consider a point on the screen located at y = 1.90 cm from the central maximum of this pattern.
(a) What is the path difference δ for the two slitsat the location y?
(b) Express this path difference in terms of the wavelength.
(c) Will the interference correspond to a maximum, a minimum, or anintermediate condition?
maximum minimum intermediate
