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

4. In a Young's double-slit experiment, the slits are separated by 0.28mm
and the screen is placed 1.4m away. The distance between the central
bright fringe and the fourth bright fringe is measured to be 1.2cm.
Determine the wavelength of light used in the experiment.
