    Two waves having the intensities in the rations of \[9:1\] produce interference. The ratio of maximum to minimum intensities is equal to:

    A)  \[10:8\]               

    B)  \[9:1\]

    C)  \[4:1\]                

    D)  \[2:1\]

    Correct Answer: C

    Solution :

    As, we know that \[\frac{{{I}_{\max }}}{{{I}_{\min }}}=\left( \frac{\sqrt{{{I}_{1}}}+\sqrt{{{I}_{2}}}}{\sqrt{{{I}_{1}}}-\sqrt{{{I}_{2}}}} \right)=\frac{4}{1}\] Because \[{{I}_{1}}:{{I}_{2}}=9:1\]
