Light with wavelength $567\,\text{nm}$ falls perpendicularly on a diffraction grating. The grating contains $400$ lines per mm. Several diffraction maxima are seen on the opposite side of the grating. What is the angular separation between the second-order maximum and the third-order maximum?
- A$13.1^{\circ}$
- B$13.9^{\circ}$
- C$15.9^{\circ}$
- D$27.0^{\circ}$
