283423 In a Young's double slit experiment, a student observes 8 fringes in a certain segment of screen when a monochromatic light of \(600 \mathrm{~nm}\) wavelength is used. If the wavelength of light is changed to \(400 \mathrm{~nm}\), then the number of fringes he would observe in the same region of the screen is

283427 In Young's double slit experiment with sodium vapour lamp of wavelength \(589 \mathrm{~nm}\) and the slits \(0.589 \mathrm{~mm}\) apart, the half angular width of the central maximum is

283428 In young's double - slit experiment, the spacing between the slits is \(d\) and wavelength of light used is \(6000 \AA\). If the angular width of a fringe formed on a distant screen is \(1^{\circ}\), then the value of \(d\) is

283429 In the ideal double-slit experiment, when a glass plate (refractive index 1.5) of thickness \(t\) is introduced in the path of one of the interfering beams (wavelength \(\lambda\) ), the intensity at the position where the central maximum occurred previously remains unchanged. The minimum thickness of the glass plate is
