So things we know-

From the slit to the screen is 140 cm

Wavelength = 500 nm

from the center of the central maximum to the first order is 3 mm.

if we use: Sin of the angle = (M * Wavelength)/d =

sin of the angle = (1 * 500x10^-7) / .003

That gives the angle of the central maximum which we can then plug into

sin angle=wavelength/slit width?
