A beam of natural light falls on a system of $5$ nicol prisms, whose transmission axis are turned, each through an angle $α = 30^{o}$ , with respect to the previous prism. The fraction of the intensity that passed through the system is

Options:

Answer:

Solution:

$I = \frac{I_{0}}{2} \times {(c o s^{2} 30)}^{4} = \frac{I_{0}}{2} \times {(\frac{3}{4})}^{4}$
$= \frac{I_{0}}{2} \times \frac{81}{256} = I_{0} \times \frac{81}{512} \approx 0.16$
