A) 5\[I\]and O
B) 5\[I\] and 3\[I\]
C) 9\[I\] and\[I\]
D) 9\[I\] and 3\[I\]
Correct Answer: C
Solution :
Maximum intensity, \[{{I}_{\max }}={{(\sqrt{{{I}_{1}}}+\sqrt{{{I}_{2}}})}^{2}}\] \[={{(\sqrt{I}+\sqrt{4I})}^{2}}=9I\] Minimum intensity \[{{I}_{\min }}={{(\sqrt{{{I}_{1}}}-\sqrt{{{I}_{2}}})}^{2}}\] \[={{(\sqrt{I}-\sqrt{4I})}^{2}}=I\]
