283531 A beam of light of wavelength \(600 \mathrm{~nm}\) from a distant source falls on a single slit \(1 \mathrm{~mm}\) wide and the resulting diffraction pattern is observed on a screen \(2 \mathrm{~m}\) away. The distance between the first dark fringes on either side of the central bright fringe is :

283538 To observe diffraction, the size of an obstacle

283544 In the diffraction of light of wavelength \(\lambda\) through single slit of width \(d\), the angle between the principal maxima and first minima will be:

283547 In a two slit experiment with monochromatic light, fringes are obtained on a screen placed at some distance from the plane of slits. If the screen is moved by \(5 \times 10^{-2} \mathrm{~m}\) towards the slits, the change in fringe width is \(\mathbf{3} \times \mathbf{1 0}^{-\mathbf{5}} \mathrm{m}\). If the distance between slits is \(10^{-3} \mathrm{~m}\), the wavelength of light will be
