A) \[\frac{I}{\sqrt{3}}\]
B) \[\sqrt{3}I\]
C) \[3I\]
D) \[\frac{I}{3}\]
Correct Answer: B
Solution :
Ratio of intensities \[\frac{{{I}_{1}}}{{{I}_{2}}}=\frac{\cos \,{{\theta }_{1}}}{\cos {{\theta }_{2}}}=\frac{\cos \,60}{\cos \,30}\] \[{{I}_{2}}=\sqrt{3}{{I}_{1}}\]You need to login to perform this action.
