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 of wavelength 650nm travels through two thin slits. The distance between the fringes produced on an
observation screen 5m away is 5mm. If the wavelength is halved and the observation screen moves to 10m, the
distance between the fringes produced on an observation screen some distance away will be:
O 1.25 mm
20 mm
O 2.5 mm
O 10 mm
O 5 mm
