A diffraction grating experiment is arranged with yellow light of wavelength $600\,\text{nm}$. The grating has a slit separation of $2.00\,\mu\text{m}$. Determine the angular separation $(\theta_2 - \theta_1)$ between the first-order and second-order maxima for the yellow light.
- A$17.5^{\circ}$
- B$19.4^{\circ}$
- C$36.9^{\circ}$
- D$54.3^{\circ}$
