A pair of slits, separated by 0.180 mm, is illuminated by light having awavelength of λ = 613 nm. An interference pattern is observedon a screen 154 cm from the slits. Consider a point on the screen locatedat y = 1.80 cm from the central maximum of this pattern.
a) What is the path difference δ for thetwo slits at 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?
