283417 A parallel beam of monochromatic light of wavelength \(400 \mathrm{~nm}\) passes through a slit 0.4 \(\mathrm{mm}\) wide and forms a diffraction pattern on a screen \(1 \mathrm{~m}\) away from the slit and parallel to it. The width of central bright band is

283419 In Young's double slit experiment the two slits are d distance apart. Interference pattern is observed on a screen at a distance \(D\) from the slits. A dark fringe is observed on the screen directly opposite to one of the slits. The wavelength of light is

283420 A monochromatic light beam of wavelength \(5896 \AA\) is used in double slit experiment to get interference pattern on a screen. \(9^{\text {th }}\) bright fringe is seen at a particular position on the screen. At the same point on the screen, If \(11^{\text {th }}\) bright fringe is to be seen, the wavelength of the light that is needed is (nearly)

283421 In Young's double slit experiment, the wavelength of the light used is doubled and distance between two slits is made half of initial distance. The resultant fringe width become
