About the course

The Physics of Atoms is one of the most fascinating and important topics in Class 12 Physics. Atoms form the foundation of modern physics, and understanding their structure is essential for mastering key concepts in board exams, JEE, and NEET.

In this course, Dr. Balaji Sampath simplifies complex atomic models, from Thomson’s model to Bohr’s model, with step-by-step explanations and real-life examples. You'll learn not only the theory but also how to apply concepts to solve tricky problems in exams.

Why this course?

Understanding atoms is the key to unlocking the mysteries of modern physics. This micro-course takes you on a deep dive into atomic structure, explaining how electrons, protons, and neutrons interact to form the building blocks of matter. You will explore Bohr’s Model, energy levels, spectral lines, and the fundamental principles that govern atomic behavior, all explained in a simple and engaging way.

Designed by Dr. Balaji Sampath for Class 12 CBSE students, this course builds a strong Physics foundation while preparing you for JEE and NEET. With expert guidance and a problem-solving approach, you'll confidently tackle numerical and conceptual questions for both school and competitive exams.

What does the course contain?

This micro-course, created by Dr. Balaji Sampath, includes 14 concept lectures and 24 questions with video solutions, all of which can be completed in just 5 hours. It covers the fundamental principles of atomic structure, including Bohr’s Model, energy levels, and spectral lines, with clear and engaging explanations. Designed for Class 12 CBSE students, the course offers practice questions from basic to advanced levels for JEE and NEET preparation. It also provides expert strategies, tips, and real-time problem-solving sessions to enhance speed and accuracy in tackling atomic physics problems.
