WebApr 6, 2024 · The width of the central maxima is nothing but the difference between the positions of the first two minima. Hence we will use the expression for the position of …
WebMay 7, 2024 · Fringe width (β) = λD/d => β ∝ λ. At the position of central maxima, Δx = 0 which is independent of the wavelength of light used. λ v < λ R , Then violet colour forms its first maxima closer to the central maxima. Central maxima for all colours coincides, since Δx = 0 for all colours formed at the same position. WebMar 29, 2013 · Expression For Fringe Width; Consider a parallel beam of light from a lens falling on a slit AB. ... We will obtain a diffraction pattern that is a central maximum at the centre O flanked by a number of dark and bright fringes called secondary maxima and minima. Central Maximum ? Each point on the plane wave front AB sends out …
WebApr 10, 2024 · Now, as is clear from the figure, the central maximum is symmetric on both sides of the central axis. Hence, the angular width $\beta $ of the central maximum will be $2\theta $. Therefore, using (3), we get, $\beta =2\theta $ $\therefore \beta =2{{\sin }^{-1}}\left( \dfrac{\lambda }{d} \right)$ --(4) Hence, we can see that the angular width of ... Web7. A more physical way of restating Ron's answer: in diffraction theory you are adding up Huygens wavelets over the aperture with appropriate phase factors. The central fringe is the only one where the entire aperture is adding in phase, i.e. constructively. The next fringe will have 2/3 adding constructively and 1/3 destructively, then after ...
