In Young's double-slit experiment, the angular width of a fringe formed on a distant screen is \( 1^{\circ} \).
\( \mathrm{P} \)
The wavelength of light used is \( 6000 \AA \). What is the spacing between the slits?
(1) \( 344 \mathrm{~mm} \)
(2) \( 0.1344 \mathrm{~mm} \)
(3) \( 0.0344 \mathrm{~mm} \)
(4) \( 0.034 \mathrm{~mm} \)
