283285 The fringe width for red colour as compared to that for violet colour is approximately

283286 At two points \(P\) and \(Q\) on screen in young's double slit experiment, waves from slits \(S_1\) and \(S_2\) have a path difference of 0 and \(\lambda / 4\) respectively. The ratio of intensities at \(P\) and \(Q\) will be:

283287 In Young's double slit experiment, light of wavelength \(480 \mathrm{~mm}\) is incident on two slits separated by a distance of \(4 \times 10^{-4} \mathrm{~m}\). If a thin plate of thickness \(1.4 \times 10^{-6} \mathrm{~m}\) and refractive index \(\frac{13}{7}\) is placed between one of the slits and screen, the phase difference introduced at the position of central maxima is

283288 In a Young's double slit experiment, the slits are separated by \(0.28 \mathrm{~mm}\) and the screen is placed \(1.4 \mathrm{~m}\) away from slits. The distance between the central bright fringe and the \(4^{\text {th }}\) order bright fringe is measured to be \(1.2 \mathrm{~cm}\). The wavelength of light used in this experiment is-
