In a two-slit experiment, monochromatic coherent light of wavelength 600 nm passes through a pair of slits separated by 2.20 x $10 ^ { - 5 }$ m. At what angle away from the centerline does the first bright fringe occur?
A)1.56°
B)2.22°
C)3.12°
D)4.70°
E)6.24°

The angle for the first bright fringe (m=1) in a two-slit experiment is given by the formula $d \sin \theta = m \lambda$. Substituting the given values: $2.20 \times 10^{-5} \sin \theta = 1 \times 600 \times 10^{-9}$, solving for $\theta$ gives approximately 1.56°.
