Thin film interference formula
Web23 Jun 2024 · With our thin-film optical coating calculator, you can easily calculate the interference in thin-films: insert the values you know: usually wavelength, thin-film … WebConstructive interference: If the path difference is an integral multiple of λ. Path difference = dsinθ = nλ, n = 0, 1, 2…, where θ is the angle between two primary maxima. Intensity variation: Slit widths of negligible size: Bright fringes are equally bright and spaced. Smaller slit separation: maxima are further apart.
