JEE Main could be held 4 times a year from 2021 to reduce the studentâs examination stress. Numbers and Quadratic Equations, Introduction If wavelength of incident light is 500 nm. The maxima are where y/D = m * lambda/d where D = distance to screen, y = distance along the screen, d = separation of slits, lambda = wavelength. We must note that in the case of the parallel plate capacitor, we ignore the fringe effect. We must also know the variance of the market return. Similarly, when ð¿ is an odd integral multiple of λ/2, the resultant fringes will be 180 0 out of phase, thus, forming a dark fringe. $$ \beta = \lambda*D/d $$ $$ where: \beta = Fringe..Width $$ $$ \lambda = Wavelength..of..light $$ $$ D= Distance..between.. the.. slits.. and.. the.. screen $$ $$ d= Distance.. between.. the.. two.. sources $$ This formula does not give any relation between the aperture of the primary source of light and the interference pattern.
