CSS Physics QUESTION #1155
Question 1
The light can totally pass through the polaroid only if the electric field vector vibrates __________ to the polarizing vector.
  • Antiparallel
  • Parallel✔️
  • Opposite
  • None of these
Correct Answer Explanation
A polaroid transmits maximum (100%) intensity when the electric field vector of the incident light is parallel to the polarizing axis of the polaroid. When they are perpendicular, transmission is zero (Malus's Law: \(I = I_0\cos^2\theta\)).
