Question
In a Young's double-slit experiment, a set of parallel slits with aseparation of 0.100 mm is illuminatedby light having a wavelength of 585 nmand the interference pattern observed on a screen 3.50 m from the slits. (a) What is the difference in path lengths fromthe two slits to the location of a fourth order bright fringe on the screen?1 µm
(b) What is the difference in path lengths from the two slits tothe location of the fourth dark fringeon the screen, away from the center of the pattern?
2 µm (a) What is the difference in path lengths fromthe two slits to the location of a fourth order bright fringe on the screen?
1 µm
(b) What is the difference in path lengths from the two slits tothe location of the fourth dark fringeon the screen, away from the center of the pattern?
2 µm
Explanation / Answer
Wavelength = 585 * 10 ^ -9 m
Distance of the screen from slits D = 3.5 m
