    In Youngs double slit experiment using sodium light \[(\lambda =5898\,\overset{\text{o}}{\mathop{\text{A}}}\,)\], 92 fringes are seen. If given colour \[(\lambda =5461\,\overset{\text{o}}{\mathop{\text{A}}}\,)\] is used, how many fringes will be seen:

    A)  99              

    B)                         85                         

    C)  67                         

    D)         62

    Correct Answer: A

    Solution :

    From the relation \[\frac{{{n}_{1}}}{{{n}_{2}}}=\frac{{{\lambda }_{1}}}{{{\lambda }_{2}}}\] \[\frac{{{n}_{1}}}{92}=\frac{5898}{5461}\] so,          \[{{n}_{1}}=99.36\approx 99\]
