In a Young's double-slit experiment, a set of parallel slits withaseparation of 0.100 mm is illuminatedby light having a wavelengthof 585 nmand the interference pattern observed on a screen 3.50 mfrom the slits.
(a) What is the difference in path lengthsfromthe two slits to the location of a fourth order bright fringeon the screen?
1 µm
(b) What is the difference in path lengths from the two slits tothelocation of the fourth dark fringeon the screen, away from thecenter of the pattern?
2 µm
