WebAnswer 1: The diffraction pattern involves a central bright fringe, also known as the central maxima. Furthermore, central maxima is surrounded by dark and bright lines known as the secondary minima and maxima. … WebMay 12, 2024 · In YDSE, the central fringe is bright, let us leave this aside for the time being from the counting procedures. On either side, the path difference Δ grows to λ / 2 first, and hence we have a dark fringe. …
WebSep 12, 2024 · The intensity of the light can be obtained using the relation I = 1 2cϵ0E2 from Electromagnetic Waves. The intensity of the maximum is then I0 = 1 2cϵ0(NΔE0)2 = 1 2μ0c(NΔE0)2, where ϵ0 = 1 / μ0c2. The phasor diagrams for the first two zeros of the diffraction pattern are shown in Figure 4.3.1b and Figure 4.3.1d. WebFor the first fringe, Δ L = λ 2 = a 2 sin θ λ = a sin θ For a ray emanating from any point in the slit, there exists another ray at a distance of a/2 that can cause destructive interference. Thus, at θ = sin−1λa, there is …
