                    nidentical waves each of intensity \[{{\operatorname{I}}_{0}}\] interfere with each other. The ratio of maximum intensities if the interference is (i) coherent and (ii) incoherent is:     JEE Main Online Paper ( Held On 23  April 2013 )

    A)                  \[{{\operatorname{n}}^{2}}\]                                  

    B)                                         \[\frac{1}{\operatorname{n}}\]

    C)                                         \[\frac{1}{{{\operatorname{n}}^{2}}}\]                               

    D)                                         \[\operatorname{n}\] 

    Correct Answer: D

    Solution :

                      \[\frac{\text{(Maximum intensity)coherent interference}}{\text{(Maximum intensity)coherent interference}}\] \[=\frac{{{n}^{2}}{{I}_{0}}}{n{{I}_{0}}}=n\]
