A) \[\frac{{{I}_{0}}}{2}\]
B) \[\frac{{{I}_{0}}}{\sqrt{2}}\]
C) \[\frac{{{I}_{0}}}{4}\]
D) \[{{I}_{0}}\]
Correct Answer: C
Solution :
Intensity, \[{{I}_{0}}={{I}_{1}}+{{I}_{2}}2\sqrt{{{I}_{1}}{{I}_{2}}}\] If \[{{I}_{1}}={{I}_{2}}=I\](Let) then \[{{I}_{0}}=4I\] When one slit is covered then \[{{I}_{2}}=0.\] \[\therefore \] \[I{{}_{0}}=I\]\[=\frac{{{I}_{0}}}{4}\]You need to login to perform this action.
