Q. No.Unpolarised light is incident from the air on a plane surface of a material of refractive index \(\mu\). At a particular angle of incidence \(i\), it is found that the reflected and refracted rays are perpendicular to each other. Which of the following options is correct for this situation?
| 1. | the reflected light is polarised with its electric vector parallel to the plane of incidence. |
| 2. | the reflected light is polarised with its electric vector perpendicular to the plane of incidence. |
| 3. | \(i = \text{sin}^{-1}\frac{1}{\mu}\) |
| 4. | \(i = \text{tan}^{-1}\frac{1}{\mu}\) |

NEET MCQ Books for XIth & XIIth Physics, Chemistry & BiologyTwo polaroids \(P_1\) and \(P_2\) are placed with their axis perpendicular to each other. Unpolarised light of intensity \(I_0\) is incident on \(P_1\). A third polaroid \(P_3\) is kept in between \(P_1\) and \(P_2\) such that its axis makes an angle \(45^\circ\) with that of \(P_1\). The intensity of transmitted light through \(P_2\) is:
1. \(\frac{I_0}{4}\)
2. \(\frac{I_0}{8}\)
3. \(\frac{I_0}{16}\)
4. \(\frac{I_0}{2}\)
