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

A screen is placed 50.2 cm from a single slit that is illuminated with light of wavelength 678 nm. If the distance between the first
and third minima in the diffraction pattern is 3.15 mm, what is the width of the slit?
