When light of an unknown polarisation is examined with a polaroid, it is found to exhibit maximum intensity \(I_0\) along \(y\)-axis and minimum intensity \(\frac{2 Y_0}{3}\) along \(x\)-axis. The intensity transmited through a polaroid with pass axis at \(45^{\circ}\) to \(y\)-axis (in \(x\) - \(y\) plane) is
- A \(\left.\frac{5}{8}\right\}_0\)
- B \(\frac{f_0}{2}\)
- C \(\frac{5}{6} f_0\)
- D \(\frac{f_0}{4}\)
Answer & Solution
Correct Answer
(C) \(\frac{5}{6} f_0\)
Step-by-step Solution
Detailed explanation
Given, maximum intensity along y axis, \[ Y_Y=Y_0 \] and minimum intensity along \(x\) axis, \[ Y_X=\frac{2 Y_0}{3} \] The intensity transmitted, through a polaroid with pass axis \(45^{\circ}\) to \(y\) axis (ie., \(45^{\circ}\) to \(x\) axis also) is given by Brewster's law,…
