Diffraction of light

In physics, the term diffraction is defined as the bending of light around the corners of the obstacle. As a light ray passes by an aperture, it bends around the edges or through slits, it spreads out through a narrow opening. The diffracted light will produce fringes of bright and dark or colored bands which are labeled as a diffraction pattern.

Question

In a Young's double slit experiment the two slits are 0.037 mm apart and the
screen is 2.52 m away from the slits. If the second order bright fringe is 6.40 cm
away from the center of the screen, what is the wavelength of the light used (in
nm)?
