$In a single-slit diffraction, the second-order bright fringe is at a distance$

In a single-slit diffraction, the second-order bright fringe is at a distance 1.40 mm from the centre of the central maximum. The screen is 80.0 cm from a slit of width 0.800 mm. Assuming that the incident light is monochromatic, the approximate wavelength of the incident light is O 5.6010-7 m 5.60107m O 7.90 x10 m O 7.9010-m
