Violet light (410 nm) and red light (685 nm) pass through a diffraction grating with d=3.33x10^-6. What is the angular separation between them for m=2

What if? physicists often measure the momentum of subatomic particles moving near the speed of light in units of mev/c, where c is the speed of light, and 1 mev = 1.6 ✕ 10−13 kg · m2/s2. based on this, what are the units of momentum for a high-speed subatomic particle in terms of fundamental si units?
