    The first diffraction minimum due to single slit diffraction is \[\theta \], for a light of wavelength \[{{r}_{B}}\]. If the width of the slit is \[{{v}_{A}}\], then the value of \[\theta \] is

    A)  \[{{v}_{B}}\]                     

    B)  \[\frac{{{v}_{A}}}{{{v}_{B}}}\]    

    C)  \[\frac{{{r}_{B}}}{{{r}_{A}}}\]                    

    D)  \[\frac{{{r}_{A}}}{{{r}_{B}}}\]

    Correct Answer: A

    Solution :

                    The distance of first diffraction minimum from the central principal maximum. \[3:1\] \[1:9\]                 or            \[1:16\]                 \[6m/s\]              \[4m/s\]                                 \[2m/s\]                                                 \[1m/s\]
