A) \[\left( \frac{{{I}_{0}}}{8} \right){{\sin }^{2}}(2\theta )\]
B) \[\left( \frac{{{I}_{0}}}{4} \right){{\sin }^{2}}(2\theta )\]
C) \[\left( \frac{{{I}_{0}}}{2} \right){{\cos }^{4}}(\theta )\]
D) \[{{I}_{0}}{{\cos }^{4}}(\theta )\]
Correct Answer: A
Solution :
Let initial intensity of light is \[{{I}_{0}}\] so, intensity of light after transmission from first polaroid \[=\frac{{{I}_{0}}}{2}\]You need to login to perform this action.
