Three discrete spectral lines occur at angles of 10.0°, 13.6°, and 15.0°, respectively, in the first-order spectrum of a diffraction grating spectrometer.
(a) If the grating has 3750 slits/cm, what are the wavelengths of the light?
| λ1 | = nm (10.0°) |
| λ2 | = nm (13.6°) |
| λ3 | = nm (15.0°) |
(b) At what angles are these lines found in the second-order
spectra?
| θ | = ° (λ1) |
| θ | = ° (λ2) |
| θ | = ° (λ3) |

A chemist identifies compounds by identifying bright lines in
their spectra. She does so by heating the compounds until they
glow, sending the light through a diffraction grating, and
measuring the positions of first-order spectral lines on a detector
15.0 cm behind the grating. Unfortunately, she has lost the card
that gives the specifications of the grating. Fortunately, she has
a known compound that she can use to calibrate the grating. She
heats the known compound, which emits light at...

1. A diffraction grating is used to separate the spectral lines
of light, emanating from a gas discharge tube (e.g., a neon light),
that is normally incident on the grating. On a screen placed 2.0 m
from the grating, the third-order (m = 3) interference maximum for
violet light (λ = 4.4 × 10−7 m) is found to be 0.20 cm farther from
the location of the central maximum (m = 0) on the screen than the
second-order maximum of...
