Lecture 3 | NCERT Examples 2.2, 2.3, 2.4 | Parallax Method, Measurement of Length, Mass & Time | Class 11 Physics | JEE/NEET

In this lecture, Ashish Sir explains important NCERT solved examples (2.2, 2.3, and 2.4) from Chapter 2 – Units and Measurements for Class 11 Physics. This session is highly useful for students preparing for IIT JEE Mains, NEET, and CBSE/State Board exams.

🔹 Key Topics Covered:

Parallax Method (NCERT Example 2.2)

-Explanation of the parallax principle and how it helps in measuring large distances that cannot be directly measured.

-Step-by-step solving of Example 2.2 with proper reasoning.

-Applications of the parallax method in astronomy and physics experiments.

2. Range of Lengths & Measurement of Length (NCERT Example 2.3)

Discussion of the range of measurable lengths in physics – from the size of subatomic particles to astronomical distances.

Methods of measuring small lengths (e.g., screw gauge, vernier calipers, optical instruments).

Solving Example 2.3 with conceptual clarity to show practical applications of these methods.

3. Measurement of Mass & Time (NCERT Example 2.4)

Explanation of how mass is measured in laboratories and advanced experiments. Time measurement using oscillations, atomic clocks, and precision instruments. Solving Example 2.4 with proper units and detailed calculations. 🔹 Concepts Highlighted by Ashish Sir: Importance of significant figures and units while solving problems. Practical techniques used in physics for measuring quantities accurately. The bridge between theoretical understanding and real-life applications of measurements. This lecture ensures that students not only learn the step-by-step solutions of NCERT examples but also gain a deeper understanding of how measurements form the foundation of experimental physics.
