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)

1) why do atoms have discrete spectral lines? 2) Is it possible for different atomic transitions, in a particular atom, to give off the same colour photons?why? 3) A beam of red photons and blue photons are sent through a diffraction grating simultaneously. Sketch the diffraction pattern of both colours. 4) The spectrometer provided is able to measure angles to a precision of 1 minute (1'). Given that 60'=1degree, convert the following angles, 31degree 21' and 12degree 5', into degrees.
