6 : Interference and Diffraction

When calculating fringe separation ((w)) in interference and diffraction problems, you can use the approximation: $(w \approx \frac{λ D}{d}),$ where λ is the wavelength of light, (D) is the distance to the screen, and (d) is the separation between the slits or sources.
This simplifies calculations when you need a quick estimate of fringe separation.
