Important Chapters in Physics for JEE Examination - Updated for 2018
The JEE (Joint Entrance Examination) is a crucial step for students aiming to pursue their higher education in engineering in India. In 2018, the examination committee introduced several changes in the syllabus, with certain chapters becoming more critical than others. This article provides a detailed analysis of these changes and highlights the key chapters that you should focus on for a strong performance in the physics section of the JEE.
Overview of Key Chapters for 2018
In 2017, the JEE examination saw a significant focus on certain chapters, with notable marks assigned. However, in 2018, some of these chapters saw a reduction in weightage, while others received increased importance. Here’s a breakdown of the chapters that you should prioritize for the JEE 2018 physics section.
Highly Weighted Chapters
1. Electricity and Magnetism
Electromagnetism: This section carried significant weightage, with a whopping 7 marks attributed to it in 2017. However, there were only 2 mark questions from this topic, indicating a relatively lower emphasis this year.
Electricity (Direct Currents): Despite seeing only 10 marks theory and 2 marks numerical from this section in 2017, it’s essential to prepare thoroughly. The topics within electricity include electrostatics, current electricity, and electromagnetic induction. Expect around 2-3 questions from this section.
2. Calorimetry and Thermal Physics
Calorimetry: In 2017, this chapter garnered 16 marks, making it one of the most important. This year, it remains critical, with a potential for up to 16 marks. Focus on understanding the principles of calorimetry and thermal expansion to ace this section.
Thermodynamics: With a weightage of 6 marks, this topic covers heat transfer, internal energy, and the laws of thermodynamics. It’s crucial to have a strong foundational knowledge to solve questions effectively. Expect 2-3 questions from this section.
3. Optics and Modern Physics
Wave and Ray Optics: Wave optics, carrying 5 marks, and ray optics, carrying 6 marks, form a significant portion. These topics include the principles of light, interference, diffraction, and polarization. Preparation for these areas should be thorough to maximize your score.
Modern Physics: This includes nuclear physics and quantum mechanics, with 5 marks each. Focus on the basics and core concepts, as these topics often appear in twisted and complex questions. Aim for 2-3 questions from this section.
4. Atomic and Nuclear Physics
Radioactivity and Nuclear Reactions: This chapter is particularly important, with a significant 16 marks attributed in 2017. While there were only 2 mark questions on radioactivity, it’s expected that this weightage will increase. Prepare well for this topic to expect a higher number of questions this year.
Semiconductors and Communication Systems: With 5 and 2 marks respectively, these topics are crucial. You need to cover the basics of semiconductors, diodes, transistors, and communication systems. Prepare well for these topics to stay ahead in the competition.
Fundamental Chapters to Strengthen Basic Knowledge
Units and Dimensions, Measurement of Errors, Vectors, Kinematics, Newton's Laws of Motion, Friction, Work Energy and Power, Electrostatics, Current Electricity, Wave Optics, Ray Optics, Centre of Mass, Momentum and Collision, Rotational Dynamics, Simple Harmonic Motion, Fluid Mechanics, Wave Mechanics and String Waves, Magnetism, and Heat Thermodynamics: These fundamental topics carry essential weightage and are crucial for building a strong base.
While these topics are not as heavily weighted in the JEE, they are fundamental for understanding more advanced concepts. Focus on these topics to ensure you have a solid grasp of the basics and can tackle higher-order questions effectively.
Additional Tips for Preparation
To excel in the JEE physics section, follow these tips:
Practice Regularly: Solving a large number of problems will not only help you understand the concepts better but also improve your speed and accuracy. Create Cheat Sheets: Use flashcards and cheat sheets to memorize important formulas and concepts. Focus on Weak Areas: Identify your weak areas and spend more time on them to ensure balanced preparation. Stay Updated: Keep track of any changes in the JEE syllabus and adjust your study plan accordingly. Mock Tests: Take regular mock tests to simulate the exam environment and improve your exam day performance.Conclusion
The JEE is an arduous challenge, but with the right preparation and focus, you can excel. Prioritize the chapters mentioned above and follow the tips provided. With dedication and hard work, you can achieve your goals and secure a place in one of the premier engineering colleges in India.
