An experiment using a diffraction grating is arranged with yellow light of wavelength $600\,\text{nm}$. The grating has a slit separation of $2.00\,\mu\text{m}$. What is 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$54.3^\circ$
