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

. Two narrow slits are separated by a distance of 1.2x 10-4 m. They are illuminated
by the light from a sodium lamp having wavelength of 589 nm. Calculate the
angular position of the first-order maximum in the interference pattern. If the light is
intercepted by a photographic film placed at a distance of 2 m from the slits, calculate
the distance between the resulting maximum and the central maximum on the film.
