Explanation / Answer

wavelength= wsin(angle)
w= how wide the slit is
the angle is going to be half of 29 degrees which is 14.5 degrees is the angle between the dark fringes with the central maximum in the center. You need the angle between the central max and one of the first dark fringes therefore you divide by two.

wavelength= (2.3*10^-3)sin(14.5) = 5.75 x 10^-4 mm

now convert to micrometers = 0.575 x 10^-6 mts
