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

Light emitted by a particular source is incident on a diffraction grating with 8000
lines/cm and produces a first-order maximum at 31°. Determine the wavelength of the
