Fsc Physics Part I, Ch-08, Malus's law

Welcome to EduVision Science Academy & Ar Physics Zone Skg!
In this lecture, we will learn Malus’s Law — a fundamental concept in Polarization of Light from Chapter 08 — FSc Part 1 Physics (New Syllabus 2025 — Pakistan).

This lecture explains:

🔹 What is Malus’s Law?
🔹 Mathematical form of Malus’s Law
🔹 Meaning of angle θ between polarizer & analyzer
🔹 Intensity of transmitted polarized light
🔹 Graphical explanation
🔹 Special cases (θ = 0°, 45°, 90° etc.)
🔹 Difference between natural & polarized light
🔹 Real-life applications of Malus’s Law
🔹 Concept-based theory + numerical understanding

The lecture is explained in very simple language so that average FSc students can understand easily — helpful for board exams, class tests & MDCAT / ECAT entry tests.
