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 is incident on a double-slit. The fourth bright band has an angular distance of 7.0° from the
central maximum. What is the distance between the slits (in um)? (Assume the frequency of the light
