An unpolarised beam of intensity \(I_{0}\) is incident on a pair of nicols making an angle of \(60^{\circ}\) with each other. The intensity of light emerging from the pair is
- A \(I_{0}\)
- B \(\dfrac{I_{0}}{4}\)
- C \(\dfrac{I_{0}}{2}\)
- D \(\dfrac{I_{0}}{8}\)
Answer & Solution
Correct Answer
(D) \(\dfrac{I_{0}}{8}\)
Step-by-step Solution
Detailed explanation
When an unpolarised beam of intensity \(I_{0}\) passes through the first nicol (polarizer), the intensity of the emerging light is reduced to half of the incident intensity. \(I_{1} = \dfrac{I_{0}}{2}\) The light emerging from the first nicol is plane-polarized. This light then…
