283155 In Young's double slit experiment, the angular width of a fringe is found to be \(0.2^{\circ}\) on screen placed \(1 \mathrm{~m}\) away. The wavelength of light used is \(600 \mathrm{~nm}\). If the entire apparatus is immersed in water of refractive index \(4 / 3\), the angular width of the fringe will be

1 \(0.18^{\circ}\)
2 \(0.12^{\circ}\)
3 \(0.15^{\circ}\)
4 \(0.06^{\circ}\)

283156 In Young's double slit experiment, the distance between the slits is \(3 \mathrm{~mm}\) and the slits are \(2 \mathrm{~m}\) away from the screen. Two interference patterns can be obtained on the screen due to light of wavelength \(480 \mathrm{~nm}\) and \(600 \mathrm{~nm}\) respectively. The separation on the screen between the \(5^{\text {th }}\) order bright fringes on the interference patterns is

1 \(4 \times 10^{-4} \mathrm{~m}\)
2 \(6 \times 10^4 \mathrm{~m}\)
3 \(12 \times 10^{-4} \mathrm{~m}\)
4 \(8 \times 10^{-4} \mathrm{~m}\)
