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 light, with wavelength of λ = 550 nm, passes through a slit and shines on a screen
that is at a distance of L = 0.30 m. The slit has a width of D = 4.0x10-6 m. Calculate
the width Y of the central bright fringe, see Figure
