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

An aperture with a diameter of 0.1 mm radiates light at 650 nm. How far from this source must
we place a screen in order to have a coherence area of 0.1 m² ?
Please enter your answer in meters in the space provided, keeping one place to the right of the
