A diffraction pattern is formed on a screen when light of wavelength 410 nm is passed through a single slit of width 1 μm. If the source light is replaced by another light of wavelength 700 nm, what should be the width of the slit so that the new light produces a pattern with the same spacing?
  1. $0.6 \textrm{ }\mu\textrm{m}$
  2. $1 \textrm{ }\mu\textrm{m}$
  3. $1.4 \textrm{ }\mu\textrm{m}$
  4. $1.7 \textrm{ }\mu\textrm{m}$
