A diffraction grating produces its first-order maximum at an angle of

12^{\circ}

when illuminated by light of wavelength

630\,\text{nm}

. The screen is

1.2\,\text{m}

from the grating. Determine the perpendicular distance on the screen between the central maximum and this first-order bright spot.
