An unpolarised beam of intensity \(I_{0}\) falls on a polaroi(d)The intensity of the emergent light is
- A \(I_{0} / 2\)
- B \(I_{0}\)
- C \(I_{0} / 4\)
- D Zero
Answer & Solution
Correct Answer
(A) \(I_{0} / 2\)
Step-by-step Solution
Detailed explanation
When an unpolarised beam of intensity \(I_{0}\) falls on a polaroid, then after polarisation, the intensity of the emergent beam of light becomes \(\frac{I_{0}}{2}\).

COMEDK 2018 Easy - Two conducting spherical shells A and B of radii 4 cm and 6 cm respectively are placed with their centres 17 cm apart in air. Initially, sphere A was given a \(-20\) nC charge while sphere B was uncharged. The spheres are then connected by a long thin conducting wire and allowed to reach electrostatic equilibrium. Assuming no charge is lost to the surroundings, the final charge on sphere A and the ratio of magnitude of electric field intensity at the surface of sphere B to that of sphere A is given by:COMEDK 2026 Medium
