In this context, you will also gain an understanding of the significance of grounding yourself. 

In addition to that, the first chapter provides you with an in-depth analysis of Coulomb’s Law and Gauss’s Law for the first time. After you finish reading the chapter, there will be an activity for you to do that will test what you’ve learned.

Chapter 2: Electrostatic Potential and Capacitance

The electrostatic potential and capacitance of various electric fields are the primary topics covered in the second chapter of this book. This chapter contains a number of formulas and derivations, all of which you will need to understand before you can answer any questions pertaining to this subject. In addition to being an essential part of the NCERT physics class 12 PDF, the calculation of the potential gradient of the external field is also included.

During the course of your study of this chapter, you will also gain an understanding of the function that capacitors play in the storage of electric charges. The difference between charge and mass as well as the definition of an electric field, are two of the topics that you will be able to gain knowledge about. You can say this as an overview.

Nevertheless, the electromagnetic spectrum, Maxwell’s equation, and displacement current are some of the most important parts of this wave. Additionally, the origins, characteristics and velocity of this wave are dissected in great detail in this chapter. At the end of each chapter, both numerical and conceptual questions are provided for your consideration. These questions are included to provide you with a preview of the types of questions that will be on the exams.

Chapter 9: Ray Optics and Optical Instruments

This chapter, along with electromagnetism and alternating current (AC), is of the utmost importance for students aspiring to pass Class 12. You will see that the majority of the physics topics are intertwined if you adhere to the NCERT 12 physics book PDF in a religious manner. As a result, you will need to handle all of the concepts with the same level of significance.

Several properties of light such as reflection and refraction, optical instruments and their mechanisms, spherical mirrors and other subjects are some of the primary topics that are covered in this chapter. Formulas and diagrams are present in this area of study, just as they are in every other area of physics. In light of the fact that these are some foundational subjects, the first thing you need to do in order to perform well on the impending comprehensive exam is to acquire a more in-depth understanding of these subjects.

Chapter 10: Wave Optics

The topic of wave optics is discussed in depth in the tenth chapter of the NCERT books for class 12 physics PDF. This chapter explains the natural behaviour and waves of light. The estimation of rays is an essential part of studying this phenomenon. In order to provide support for this, the first thing you need to do is educate yourself on Maxwell’s electromagnetic theory and Huygens’ wave theory.
