Light emitted by element \(X\) passes through a diffraction grating that has 1200 slits \(/ \mathrm{mm}\). The interference pattern is observed on a screen \(75.0 \mathrm{~cm}\) behind the grating. First-order maxima are observed at distances of \(56.2 \mathrm{~cm}, 65.9 \mathrm{~cm}\), and \(93.5 \mathrm{~cm}\) from the central maximum. What are the wavelengths of light emitted by element \(\mathrm{X}\) ?
