<Dl> <Dd> m λ = d sin ⁡ θ (\ displaystyle m \ lambda = d \ sin \ theta) </Dd> </Dl> <Dd> m λ = d sin ⁡ θ (\ displaystyle m \ lambda = d \ sin \ theta) </Dd> <P> where d (\ displaystyle d) is the separation between two wavefront sources (in the case of Young's experiments, it was two slits), θ (\ displaystyle \ theta) is the angular separation between the central fringe and the m (\ displaystyle m) th order fringe, where the central maximum is m = 0 (\ displaystyle m = 0). </P> <P> This equation is modified slightly to take into account a variety of situations such as diffraction through a single gap, diffraction through multiple slits, or diffraction through a diffraction grating that contains a large number of slits at equal spacing . More complicated models of diffraction require working with the mathematics of Fresnel or Fraunhofer diffraction . </P>
