[单选题]
A parallel beam of lig t,jds*hgm/k9l6q0sght with a zl bjn0 as1my/qf-6h8kb .0ekwavelength of $500\,nm$ passes through a narrow slit with a slit width of $2\,μm$. The angle of diffraction for the first minimum is θ. What is the new angle of diffraction for the first minimum when the slit width is changed to $4\,μm$ and the wavelength of the light is now $250\,nm$?
A. 2θ
B. θ
C. $\frac{θ}{2}$
D. $\frac{θ}{4}$
