A diffraction grating contains $4.00 \times 10^5$ lines per metre. Light with wavelength $589 \times 10^{-9}\,\text{m}$ falls normally on the diffraction grating. What is the angle between the second-order maximum and the line of travel of the incident beam of light?
- A$13.6^\circ$
- B$27.3^\circ$
- C$28.1^\circ$
- D$56.2^\circ$
