A) \[9I\] and\[I\]
B) \[9I\]and\[4I\]
C) \[16I\]and\[4I\]
D) \[16I\]and\[I\]
Correct Answer: C
Solution :
Given,\[{{I}_{1}}=I\]and \[{{I}_{2}}=9I\] Maximum intensity \[={{(\sqrt{{{I}_{1}}}+\sqrt{{{I}_{2}}})}^{2}}\] \[={{(\sqrt{I}+\sqrt{9I})}^{2}}\] \[=16I\] Minimum intensity \[={{(\sqrt{{{I}_{1}}}-\sqrt{{{I}_{2}}})}^{2}}\] \[={{(\sqrt{I}-\sqrt{9I})}^{2}}=4I\]
