Wave Optics

In Young's double slit experiment, \(8^{\text {th }}\) maximum with wavelength '\(\lambda_1\)' is at a distance '\(d_1\)' from the central maximum and \(6^{\text {th }}\) maximum with wavelength '\(\lambda_2\)' is at a distance '\(\mathrm{d}_2\)'. Then \(\frac{\mathrm{d}_2}{\mathrm{~d}_1}\) is
