An unpolarised light beam strikes a glass surface at Brewster's angle. Then

- The reflected light will be partially polarised.
- The refracted light will be completely polarised.
- Both the reflected and refracted light will be completely polarised.
- The reflected light will be completely polarised but the refracted light will be partially polarised.
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
At Brewster’s angle, the reflected light becomes completely polarised perpendicular to the plane of incidence. This happens because the angle between the reflected and refracted rays becomes \(90\degree\) . The refracted light, however, remains partially polarised because it contains components of both polarisation states.

- In finding out the refractive index of the glass slab, the following observations were made through a travelling microscope: 50 vernier scale divisions (VSD), 49 MSD, 20 divisions on the main scale in each cm. For the mark on paper: \[ \text{MSR} = 8.45 \, \text{cm}, \quad \text{VC} = 26 \] For the mark on paper seen through the slab: \[ \text{MSR} = 7.12 \, \text{cm}, \quad \text{VC} = 41 \] For the powder particle on the top surface of the glass slab: \[ \text{MSR} = 4.05 \, \text{cm}, \quad \text{VC} = 1 \] (MSR = Main Scale Reading, VC = Vernier Coincidence) Refractive index of the glass slab is:

Questions Asked in NEET exam
- Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : The potential (V) at any axial point, at 2 m distance(r) from the centre of the dipole of dipole moment vector \(\vec{P}\) of magnitude, 4 × 10-6 C m, is ± 9 × 103 V.
(Take \(\frac{1}{4\pi\epsilon_0}=9\times10^9\) SI units)
Reason R : \(V=±\frac{2P}{4\pi \epsilon_0r^2}\), where r is the distance of any axial point, situated at 2 m from the centre of the dipole.
