wavelength = 675 nanometer


\begin{gathered} \wedge=675nm \\ \text{Convert to mm} \\ \wedge=0.000675\operatorname{mm} \end{gathered}

Therefore,


\begin{gathered} d\sin 0.111=m\wedge \\ d=(m\wedge)/(\sin0.111) \\ d=(1*0.000675)/(0.00193731425*2) \\ d=(0.000675)/(0.00193731425*2) \\ d=0.17421063226\operatorname{mm} \\ d=0.174\operatorname{mm} \end{gathered}
