Three discrete spectral lines occur at angles of 10.1, 13.7, and 14.8, respectively, in the first-order spectrum

Question:

Three discrete spectral lines occur at angles of 10.1°, 13.7°, and 14.8°, respectively, in the first-order spectrum of a diffraction-grating spectrometer.
(a) If the grating has 3 660 slits/cm, what are the wavelengths of the light?
(b) At what angles are these lines found in the second order spectra?
