Three discrete spectral lines occur at angles of 10.2°, 13.5°, and 14.6°, respectively, in the first-order spectrum of a diffraction grating spectrometer.

(a) If the grating has 3780 slits/cm, what are the wavelengths of the light?

λ₁	= nm (10.2°)
λ₂	= nm (13.5°)
λ₃	= nm (14.6°)

(b) At what angles are these lines found in the second-order spectra?

θ	= ° (λ₁)
θ	= ° (λ₂)
θ	= ° (λ₃)
