As an admirer of Thomas Young, you perform a double-slit experiment in his honor. You set your slits 1.01 mm apart and position your screen 3.09 m from the slits. Although Young had to struggle to achieve a monochromatic light beam of sufficient intensity, you simply turn on a laser with a wavelength of 639 nm . How far on the screen are the first bright fringe and the second dark fringe from the central bright fringe

Explanation:

m = Order = 1

D = Distance between screen and slit = 3.09 m

d = Slit distance = 1.01 mm

= Wavelength = 639 nm

Distance from the first bright fringe from the central bright fringe is given by

Distance from the first bright fringe from the central bright fringe is

Distance from the second dark fringe from the central bright fringe is given by

Distance from the second dark fringe from the central bright fringe is .
